EXECUTIVE SUMMARY

The management goal for the Clearwater Spring Chinook salmon population is to provide sustainable fishing opportunity and to enhance the natural spawning population. While the Spring- and Summer-Run Chinook Salmon Ecological Significant Unit (ESU) was listed as threatened under the Endangered Species Act (ESA) on August 22, 1992, the non-indigenous hatchery spring-run Chinook stocks currently found in the Clearwater River and its tributaries are not listed under the ESA because the historical populations in the basin were likely extirpated following construction of Lewiston Dam in 1927.

The purpose of the Clearwater River spring Chinook hatchery program is to mitigate for fish losses caused by the construction and operation of the four lower Snake River federal dams. The hatchery mitigation program is a federally authorized mandate to annually return 12,000 adult spring Chinook salmon to stream reaches upstream of after harvest of 48,000 adults by commercial and sport fisheries in the ocean, the and the lower Snake River. Current hatchery production and supplementation efforts from this program are consistent with the 2008-2017 US vs. Oregon Management Agreement. Fish culture is performed at the Clearwater Hatchery. Broodstock collection occurs at the Red River, Crooked River, and the Powell satellite facilities and at Kooskia Hatchery (Clear Creek). Hatchery operations and monitoring activities are funded by the Bonneville Power Administration through the Lower Snake River Compensation Plan (LSRCP). Where appropriate, other sources of funding for monitoring activities are identified.

Juvenile releases from the segregated programs will occur in the (400,000 spring- run smolts); (400,000 spring-run smolts and 300,000 spring-run parr); Red River (SF Clearwater) (1.1 million spring-run smolts); Clear Creek (235,000 spring-run smolts); and Crooked River (200,000 summer-run smolts). Locally adapted broodstock will be used for the Lochsa River, South Fork Clearwater and Clear Creek programs. Broodstock from one of these sites will be used for releases in the Selway River program until such time as infrastructure is in place to collect broodstock in the Selway River.

This mitigation program has never achieved the escapement goal of 12,000 adults to the project area since the inception of the program. Based on the most recent 10 year geometric mean SAR of 0.34% to Lower Granite dam (Red River, Crooked River and Powell combined), the production capacity at this facility needs to be increased to 3.5 million yearling smolts to return 12,000 adults to the project area under recent Columbia River harvest schedules.

Early in the program, managers agreed (through the USvOR process) to scale back the steelhead production goals that were originally modeled for the program to meet the mitigation goal of returning 14,000 steelhead back to Lower Granite Dam. This reduction in steelhead production provided additional rearing space for Chinook salmon at Clearwater Fish Hatchery. Managers have prioritized the use of that space to increase the production of spring- and summer-run Chinook salmon at Clearwater Fish Hatchery.

The original production target for spring Chinook salmon was 1.4 million yearling smolts. Currently, 2,135,000 spring-run Chinook yearling smolts are reared at Clearwater Fish Hatchery.

Page 2

Of the total release, 135,000 smolts are not adipose fin clipped and do not contribute to mark selective fisheries. Additionally, 500,000 subyearling spring Chinook salmon, primarily intended for supplementation, are reared at Clearwater Fish Hatchery.

In addition to the existing spring Chinook program, managers have initiated the development of a locally adapted summer-run Chinook salmon population in the Clearwater River. Anecdotal accounts of wild Chinook returns to Clearwater basin prior to their extirpation suggest that they may have included both spring- and summer-run populations. IDFG, the Tribe, and the LSRCP initiated a program in 2009 to evaluate the potential of building a locally adapted hatchery population and supplement naturally spawning summer-run Chinook salmon populations in the Clearwater River drainage. Eggs from the harvest portion of the McCall Hatchery program on the South Fork Salmon River are being incubated and reared at the Clearwater Fish Hatchery. The smolts will be released in the Crooked River in the upper South Fork Clearwater drainage. Adult returns from those releases will be trapped at the Clearwater Hatchery Crooked River trapping facility and used to develop a locally adapted and fully independent summer-run broodstock for subsequent harvest and supplementation releases in the Selway and South Fork Clearwater rivers. Egg transfers from the McCall Hatchery will cease once a locally adapted broodstock is developed in the Clearwater River.

Key performance standards for the program will be tracked in a targeted monitoring and evaluation program. These standards include: (1) abundance and composition of natural spawners and hatchery broodstock (pHOS, pNOB, and PNI); (2) number of smolts released; (3) in-hatchery and post-release survival rates; (4) total age specific adult recruitment, harvest and escapement of the natural and hatchery components; and (5) abundance, productivity, diversity and spatial structure of the naturally spawning Chinook populations.

SECTION 1. GENERAL PROGRAM DESCRIPTION

1.1 NAME OF HATCHERY OR PROGRAM

Hatchery: Clearwater Fish Hatchery

Program: Clearwater Spring Chinook

1.2 SPECIES AND POPULATION (OR STOCK) UNDER PROPAGATION, AND ESA STATUS

The species being propagated is Spring Chinook salmon (Oncorhynchus tshawytscha).

The Snake River Spring- and Summer-Run Chinook Salmon ESU was listed as threatened under the Endangered Species Act (ESA) on August 22, 1992 and reaffirmed on June 28, 2005. The ESU includes those fish that spawn in the Snake River drainage and its major tributaries, including the Grande Ronde River and the Salmon River, and that complete their adult, upstream migration (passing Bonneville Dam) between March and July. The non-indigenous hatchery spring- and summer-run Chinook stocks currently used in the Clearwater River and its tributaries are not considered part of the ESU (57 FR 14653). Native spring Chinook salmon were likely

1.5 LOCATION(S) OF HATCHERY AND ASSOCIATED FACILITIES

Clearwater Fish Hatchery - The program consists of the main hatchery and three satellite facilities. The Clearwater Fish Hatchery is located at confluence of the North Fork and mainstem Clearwater rivers, river kilometer 65 on the Clearwater River; 121 Page 5

kilometers upstream from Lower Granite Dam, and 842 kilometers upstream from the mouth of the Columbia River. The Hydrologic Unit Code is 17060300800100.00.

Red River - The Red River satellite facility is located at river kilometer 27 of the Red River, a tributary to the South Fork of the Clearwater River at river kilometer 101. The facility is 310 kilometers upstream from Lower Granite Dam and 1,030 kilometers from the mouth of the Columbia River. The Red River pond was built in 1977 under the Columbia River Fisheries Development Project and was administered by NMFS, IDFG, USFS, and the Pacific Northwest Regional Commission until 1986. In 1986, a permanent adult trapping facility and holding complex was constructed by the U.S. Army Corps of Engineers as part of the LSRCP.

Crooked River - The Crooked River satellite facility is located at river kilometer 1 of Crooked River, also a tributary to the South Fork Clearwater River at river kilometer 94. The facility is 287 kilometers upstream from Lower Granite Dam and 1,007 kilometers upstream from the mouth of the Columbia River. The Crooked River satellite has been in operation since 1990.

Powell - The Powell satellite facility is located at the headwaters of the Lochsa River (river kilometer 0), at the confluence of Brushy Fork Creek and Colt Killed Creek (previously White Sand Creek). The Lochsa River is a tributary to the Middle Fork Clearwater. The satellite facility is 320 kilometers upstream from Lower Granite Dam and 1,040 kilometers upstream from the mouth of the Columbia River.

1.6 TYPE OF PROGRAM

This hatchery program is operated as a segregated harvest program. A component of the program (approximately 17% of the current production) is intended to provide a supplementation benefit consistent with the 2008-2017 US vs. OR Management Agreement. Clearwater hatchery also conducts early rearing for spring Chinook salmon (200,000) that are transferred to the Nez Perce Tribal Fish Hatchery (NPTH) and subsequently reared to full-term smolts and released from the NPTH into the mainstem Clearwater River.

1.7 PURPOSE (GOAL) OF THE PROGRAM

The management goals for the Clearwater River spring Chinook populations are to provide sustainable fishing opportunities and to increase the abundance of the natural populations. These populations are not listed under the Endangered Species Act because the wild populations in the basin were likely extirpated following construction of Lewiston Dam in 1927.

The purpose of the Clearwater River spring Chinook hatchery program is to mitigate for fish losses caused by the construction and operation of the four lower Snake River federal dams. The hatchery mitigation program is a federally authorized mandate to annually return 12,000 adult spring Chinook salmon to stream reaches upstream of Lower Granite Dam after a harvest of 48,000 in downstream fisheries. Hatchery production for harvest mitigation and supplementation efforts from this program are also mandated in US vs. Oregon. Fish culture is performed at the Clearwater Hatchery, Red River Satellite Facility, Crooked River Satellite Facility, and the Powell Satellite Facility. All hatchery operations and monitoring activities are

Page 6

funded by the Bonneville Power Administration through the Lower Snake River Compensation Plan.

The Clearwater River spring/summer Chinook hatchery program is part of the Lower Snake River Compensation Plan (LSRCP), a congressionally mandated program pursuant to PL 99-662. The purpose of the LSRCP is to replace adult salmon, steelhead and lost by construction and operation of four hydroelectric dams on the Lower Snake River. Specifically, the stated purpose of the plan is:

“…[to]….. provide the number of salmon and steelhead trout needed in the Snake River system to help maintain commercial and sport fisheries for anadromous species on a sustaining basis in the Columbia River system and Pacific Ocean” (NMFS & USFWS 1972 pg 14)

Specific mitigation goals for the LSRCP were established in a three step process. First, the adult escapement that occurred prior to construction of the four dams was estimated. Second, an estimate was made of the reduction in adult escapement (loss) caused by construction and operation of the dams (e.g. direct mortality of smolt). Third, a catch to escapement ratio was used to estimate the future production that was forgone in commercial and recreational fisheries as result of the reduced spawning escapement and habitat loss. Assuming that the fisheries below the project area would continue to be prosecuted into the future as they had in the past, LSRCP adult return goals were expressed in terms of the adult escapement back to, or above the project area. Other than recognizing that the escapements back to the project area would be used for hatchery broodstock, no other specific priorities or goals were established in the enabling legislation or supporting documents regarding how these fish might be used. For spring Chinook salmon the escapement above Lower Granite Dam prior to construction of these dams was estimated at 122,200 adults. Based on a 15% mortality rate for smolts transiting each of the four dams (48% total mortality) the expected reduction in adults subsequently returning to the area above Lower Granite Dam was 58,700. This number established the LSRCP escapement mitigation goal. This reduction in natural spawning escapement was estimated to result in a reduction in the coast-wide commercial/tribal harvest of 176,100 adults, and a reduction in the recreational fishery harvest of 58,700 adults below the project area. In summary the expected total number of adults that would be produced as part of the LSRCP mitigation program was 293,500.

Component Number of Adults Escapement above Lower Granite Dam 58,700 Commercial Harvest 176,100 Recreational Harvest 58,700 Total 293,500

Since 1976 when the LSRCP was authorized, many of the parameters and assumptions used to size the hatchery program and estimate the magnitude and flow of benefits have changed. The survival rate required to deliver a 4:1 catch to escapement ratio has been less than expected and this has resulted in fewer adults being produced. The listing of Spring Chinook under the Endangered Species Act has resulted in significant curtailment of commercial, recreational and tribal fisheries throughout the

Page 7

mainstem Columbia River. This has resulted in a higher percentage of the annual run returning to the project area than was expected. The U.S. v. Oregon court stipulated Fishery Management Plan has established specific hatchery production agreements between the states, tribes and federal government. This agreement has substantially diversified the spring Chinook hatchery program by adding new off-station releases sites and stocks designed to meet short term conservation objectives. The Clearwater River spring Chinook salmon mitigation program was designed to escape 12,000 adults back to the project area after a harvest of 48,000. While recognizing the overarching purpose and goals established for the LSRCP, and realities’ regarding changes since the program was authorized, the following objectives for the beneficial uses of adult returns have been established for the period through 2017:

1. To contribute to the recreational, commercial and/or tribal fisheries in the mainstem Columbia River consistent with agreed to abundance based harvest rate schedules established in the 2008 – 2017 U.S. vs. Oregon Management Agreement. 2. To collect approximately 1900 spring-run and 120 summer-run adult broodstock to perpetuate this hatchery program (see sections 6-8 for more detail). 3. To provide recreational and tribal tributary fisheries annually (see Section 3.3 for more detail). 4. To utilize hatchery-origin adults for supplementing the natural population.

To maximize the beneficial uses of fish that return to the project area that are not used for broodstock, harvest or natural spawning, managers have developed agreements to share and distribute these fish equally between tribal and non-tribal entities. Specific objectives are established annually as part of a preseason co-manager meeting between the states, tribes and federal agencies to prioritize the distribution of fish, Specific dispositions may include: a. Tribal subsistence b. Recycling fish back through terminal fisheries c. Donations to food banks and charitable organizations d. Outplanting for natural spawning e. Nutrient enhancement

1.8 JUSTIFICATION OF PROGRAM

The Clearwater River spring/summer Chinook hatchery program is part of the Lower Snake River Compensation Plan (LSRCP), a congressionally mandated program pursuant to PL 99-662. The purpose of the LSRCP is to replace adult salmon, steelhead and rainbow trout lost by construction and operation of four hydroelectric dams on the Lower Snake River.

Segregated harvest type programs will be operated in the Lochsa River (400,000 smolts), Selway River (400,000 smolts, 300,000 parr), South Fork Clearwater River (1.1 million smolts) and Clear Creek (235,000 smolts). Locally adapted broodstock will be used for the Lochsa River, South Fork Clearwater and Clear Creek programs. Non-locally adapted broodstock will be used for the Selway River program until such time as infrastructure is in place to collect broodstock

locally. A component of the Clearwater Fish Hatchery production capacity is utilized to provide a supplementation benefit in the Selway River. This production is identified in the 2008-2017 USvOR Management Agreement.

1.9 LIST OF PROGRAM PERFORMANCE STANDARDS

“Performance Standards” are designed to achieve the program goal/purpose, and are generally measurable, realistic, and time specific. The NPPC “Artificial Production Review” document attached with the instructions for completing the HGMP presents a list of draft “Performance Standards” as examples of standards that could be applied for a hatchery program. If an ESU-wide hatchery plan including your hatchery program is available, use the performance standard list already compiled.

Upon review of the NPCC “Artificial Production Review” document (2001) we have determined that this document represents the common knowledge up to 2001 and that the utilization of more recent reviews on the standardized methods for evaluation of hatcheries and supplementation at a basin wide ESU scale was warranted.

A NPCC “Artificial Production Review” document (2001) provides categories of standards for evaluating the effectiveness of hatchery programs and the risks they pose to associated natural populations. The categories are as follows: 1) legal mandates, 2) harvest, 3) conservation of wild/naturally produced spawning populations, 4) life history characteristics, 5) genetic characteristics, 6) quality of research activities, 7) artificial production facilities operations, and 8) socio-economic effectiveness. The NPCC standards represent the common knowledge up to 2001.

In a report prepared for Northwest Power and Conservation Council, the Independent Scientific Review Panel (ISRP) and the Independent Scientific Advisory Board (ISAB) reviewed the nature of the demographic, genetic and ecological risks that could be associated with supplementation, and concluded that the current information available was insufficient to provide an adequate assessment of the magnitude of these effects under alternative management scenarios (ISRP and ISAB 2005). The ISRP and ISAB recommended that an interagency working group be formed to produce a design(s) for an evaluation of hatchery supplementation applicable at a basin-wide scale. Following on this recommendation, the Ad Hoc Supplementation Workgroup (AHSWG) was created and produced a guiding document (Galbreath et al. 2008) that describes framework for integrated hatchery research, monitoring, and evaluation to be evaluated at a basin-wide ESU scale.

The AHSWG framework is structured around three categories of research monitoring and evaluation: 1) implementation and compliance monitoring, 2) hatchery effectiveness monitoring, and 3) uncertainty research. The hatchery effectiveness category addresses regional questions relative to both harvest augmentation and supplementation hatchery programs and defines a set of management objectives for specific to supplementation projects. The framework utilizes a common set of standardized performance measures as established by the Collaborative Systemwide Monitoring and Evaluation Project (CSMEP). Adoption of this suite of performance measures and definitions across multiple study designs will facilitate coordinated analysis of findings from regional Page 9

monitoring and evaluation efforts aimed at addressing management questions and critical uncertainties associated with relationships between harvest augmentation and supplementation hatchery production and ESA listed stock status/recovery.

The NPCC (2006) has called for integration of individual hatchery evaluations into a regional plan. While the RM&E framework in AHSWG document represents our current knowledge relative to monitoring hatchery programs to assess effects that they have on population and ESU productivity, it represents only a portion of the activities needed for how hatcheries are operated throughout the region. A union of the NPCC (2001) hatchery monitoring and evaluation standards and the AHSWG framework likely represents a larger scale more comprehensive set of assessment standards, legal mandates, production and harvest management processes, hatchery operations, and socio-economic standards addressed in the 2001 NPCC document (sections 3.1, 3.2, 3.7, and 3.8 respectively). These are not addressed in the AHSWG framework and should be included in this document. NPCC standards for conservation of wild/natural populations, life history characteristics, genetic characteristics and research activities (sections 3.3, 3.4, 3.5, and 3.6 respectively) are more thoroughly in the AHSWG and the later standards should apply to this document. Table 1 represents the union of performance standards described by the Northwest Power and Conservation Council (NPCC 2001), regional questions for monitoring and evaluation for harvest and supplementation programs, and performance standards and testable assumptions as described by the Ad Hoc Supplementation Work Group (Galbreath et al. 2008).

1.11 EXPECTED SIZE OF PROGRAM

1.11.1Proposed annual broodstock collection level (maximum number of adult fish)

The current spring/summer Chinook salmon program at the Clearwater Hatchery includes the release of 2,635,000 spring-run Chinook salmon and 200,000 summer-run Chinook salmon. To achieve these release goals, approximately 950 spring-run and 60 summer-run females are collected for broodstock and a similar number of males are collected. Additionally, IDFG provides eggs from up to 200 females to the Nez Perce Tribe for programs operated in the Clearwater River drainage.

South Fork Clearwater River Program – Red River and Crooked River traps (IDFG mitigation program): Approximate adult spawn target: 470 females (approximately 1.88 million green eggs).

South Fork Clearwater River Program – Red River and Crooked River traps (Nez Perce Tribal supplementation program): The Nez Perce Tribe requests eggs from up to 200 females.

Lochsa River Program – Powell trap (IDFG mitigation program): Approximate adult spawn target: 483 females (approximately 1.94 million eggs).

1.11.2 Proposed annual fish release levels (maximum number) by life stage and location

Information presented in Table 2 was taken from the brood year 2004 IDFG spring Chinook salmon mark plan. Generally, the number of adipose fin-clipped juvenile salmon is relatively stable from year-to-year. However, the number of fish dedicated to other management objectives may vary from year-to-year.

1.13 DATE PROGRAM STARTED (YEARS IN OPERATION)

The Clearwater Fish Hatchery was completed and became operational in the fall of 1991. Completion dates of the satellite facilities are: Powell – 1989, Red River - 1976, and Crooked River - 1990. The Red River facility was originally constructed in 1976 under the Columbia Basin Development Program and was modified in 1986 under the Lower Snake River Compensation Program.

1.14 EXPECTED DURATION OF PROGRAM

This program is expected to continue indefinitely to provide mitigation under the Lower Snake River Compensation Plan.

1.15 WATERSHEDS TARGETED BY PROGRAM

Listed by hydrologic unit code –

Clearwater River, Idaho: 17060306 South Fork Clearwater River: 17060305 Lochsa River: 17060303

1.16 INDICATE ALTERNATIVE ACTIONS CONSIDERED FOR ATTAINING PROGRAM GOALS

As mentioned earlier, the Clearwater Fish Hatchery was constructed to mitigate for fish losses caused by construction and operation of the four lower Snake River federal hydroelectric dams. The Clearwater Fish Hatchery has a federally authorized goal of returning 12,000 adult spring Chinook salmon to reaches upstream of Lower Granite Dam after a harvest of 48,000. The Idaho Department of Fish and Game’s objective is to ensure that harvestable components of hatchery- produced Chinook salmon are available to provide fishing opportunities, consistent with meeting spawning escapement and preserving the genetic integrity of natural populations (IDFG 1992).

This mitigation program has never achieved the escapement goal of 12,000 adults to Lower Granite Dam since the inception of the program. Based on the most recent 10 year geometric mean SAR of 0.34% to Lower Granite dam, the production capacity at this facility needs to be increased to 3.5 million yearling smolts to return 12,000 adults to the project area under current Columbia River harvest schedules.

Early in the program, managers agreed (through the USvOR process) to scale back the steelhead production goals that were originally modeled for the program to meet the mitigation goal of returning 14,000 steelhead back to Lower Granite Dam. This reduction in steelhead production left vacant rearing space at Clearwater Fish Hatchery. Managers have prioritized the use of that space to increase the production of spring and summer run Chinook salmon at Clearwater Fish Hatchery.

Page 16

The original production target for spring Chinook salmon was 1.4 million yearling smolts. Currently, 2,135,000 yearling spring Chinook smolts are reared at Clearwater Fish Hatchery. All but 135,000 of these are adipose fin clipped. Additionally, 500,000 subyearling spring Chinook salmon are released at Clearwater Fish Hatchery.

In addition to the existing the spring Chinook program, managers are developing a locally adapted summer-run Chinook population in the Clearwater River. Anecdotal accounts of wild Chinook returns to Clearwater basin prior to their extirpation suggest that they may have included both spring and summer run populations. IDFG, the Nez Perce Tribe, and the LSRCP initiated a program in 2009 to evaluate the possibility of building a locally adapted hatchery in the Clearwater River drainage. Eggs from the harvest portion of the McCall Hatchery summer run Chinook salmon program on the South Fork Salmon River are being incubated and reared at the Clearwater Fish Hatchery. The smolts will be released in the Crooked River in the upper South Fork Clearwater drainage. Adult returns from those releases will be trapped at the Crooked River trapping facility and used to develop a locally adapted and fully independent summer run broodstock for subsequent harvest and supplementation releases in the Selway and South Fork Clearwater rivers. Egg transfers from the McCall Hatchery will cease once a locally adapted broodstock is developed. Currently, Clearwater Fish Hatchery is rearing 200,000 summer run Chinook salmon with the eventual goal of releasing 1,000,000 summer run yearling Chinook Salmon. Once this goal is reached, Clearwater Fish Hatchery will be releasing 3,135,000 yearling, and 500,000 subyearling Chinook salmon. Once the summer run broodstock is established, the long term goal is to move the summer run program to the Selway River. In order to accomplish this, a broodstock collection facility will be needed in the Selway River drainage.

This HGMP does not reflect the facility and personnel needs that would be required to fully develop the one million summer-run Chinook salmon smolt program. Instead, this HGMP addresses needs to operate the program under status quo as described in the Executive Summary. This includes maintaining 2,135,000 spring run yearling smolts and 500,000 sub-yearling spring run Chinook Salmon and 200,000 yearling summer-run Chinook salmon.

It should be noted that a significant proportion of the natural production monitoring conducted by IDFG that occurs in the upper South Fork Clearwater River and upper Lochsa River is funded through an ongoing BPA funded supplementation research project (Bowles and Leitzinger 1991, BPA Project Number: 1989-098-00). This project is expected to sunset in 2014 and in order to continue monitoring the natural population in these areas, additional funds will be required.

Recommendations from the USFWS Hatchery Review Team (HRT) Recommendations

The HRT provided several potential programmatic alternatives to the current hatchery program along with their recommendation for the preferred alternative. For the Clearwater Fish Hatchery spring Chinook salmon program, the HRT preferred alternative is for the managers to shift a component of production releases to the North Fork Clearwater River and reduce the releases in the Lochsa and South Fork Clearwater rivers. In the short term the focus would be to develop integrated/conservation broodstocks in these areas. In the long term, the focus would shift to developing stepping stone broodstocks in an attempt to shift mitigation production back to the Lochsa and South Fork Clearwater rivers.

Page 17

Managers considered all the alternatives presented by the HRT and believe that the segregated program does not pose significant risk to the natural populations in the Clearwater drainage. In addition , natural populations in the Clearwater River are not part of the Snake River spring/summer Chinook salmon ESU and current natural populations are a direct result of the hatchery program. Managers will continue to implement best management practices associated with operation of the hatcheries and restoration of natural populations.

In addition to the programmatic recommendations, the review team also provided specific recommendations across eight categories: Program Goals and Objectives; Broodstock Choice and Collection; Hatchery and Natural Spawning; Incubation and Rearing; Release and Outmigration; Facilities and Operations; Research, Monitoring and Accountability; and Education and Outreach. Reponses from the managers for each of the recommendations are provided in Appendix B.

2.2.1 Description of NMFS ESA-listed salmonid population(s) affected by the program

No wild/natural, ESA-listed spring Chinook salmon adults or juveniles are collected or directly affected as part of the Clearwater Fish Hatchery mitigation program described in this HGMP.

The following information on the present status of Clearwater River basin spring Chinook salmon was taken from the Draft Clearwater Subbasin Summary for the Clearwater Subbasin of the Mountain Snake Province (NPPC 2001).

Indigenous Chinook salmon in the Clearwater River subbasin were eliminated by Lewiston Dam (Schoen et al. 1999; Murphy and Metsker 1962). However, naturalized populations of spring Chinook salmon have been re-established in some portions of the subbasin as a result of reintroduction efforts (Schoen et al. 1999; Larson and Mobrand 1992).

Page 18

Spring Chinook salmon within the Clearwater subbasin are excluded from the ESU encompassing other spring/summer stocks throughout the Snake River basin, but represent an important effort aimed at restoring an indigenous fish population to an area from which they had been extirpated. Efforts to reestablish spring Chinook salmon in the subbasin were extensive and have previously been summarized by Nez Perce Tribe and Idaho Department of Fish and Game (1990), Cramer and Neeley (1992), and Cramer (1995), and Bowles and Leitzinger (1991). Currently hatchery spring Chinook are released for harvest mitigation and to supplement natural production (Nez Perce Tribe and Idaho Department of Fish and Game 1990; Idaho Department of Fish and Game 2001).

Reintroduction of spring Chinook salmon following removal of the Lewiston Dam has resulted in naturally reproducing runs in Lolo Creek, and mainstems and tributaries of the Lochsa, Selway, and South Fork Clearwater Rivers (Larson and Mobrand 1992). Founding hatchery stocks used for spring Chinook salmon reintroductions were primarily obtained from the Rapid River Hatchery (Kiefer et al. 1992; Nez Perce Tribe and Idaho Department of Fish and Game 1990). Initially however, spring Chinook stocks imported for restoration came from Carson, Big White, Little White or other spring Chinook captured at Bonneville Dam (Nez Perce Tribe and Idaho Department of Fish and Game 1990). Genetic analyses confirm that existing natural spring Chinook salmon in the Clearwater River subbasin are derived from reintroduced Snake River stocks (Matthews and Waples 1991).

Spring Chinook salmon enter the Columbia River and begin spawning migrations during April and May, reaching the Clearwater subbasin from April through July (Nez Perce Tribe and Idaho Department of Fish and Game 1990). Spring Chinook salmon indigenous to the Snake River basin tend to spawn earlier and higher in elevation than summer (early-fall) and fall races (Chapman et al. 1991). Spawning of spring stocks typically occurs in tributaries and headwater streams in August and September. Eggs hatch in December with emergence complete by April (Nez Perce Tribe and Idaho Department of Fish and Game 1990; U.S. Fish and Wildlife Service 1999). Spring Chinook salmon remain in freshwater for one year, migrating to the ocean in the spring of their second year, typically from March through June (U.S. Fish and Wildlife Service 1999; Walters et al. 2001). Nearly all adult spring and summer Chinook that return to the Snake River basin result from fish that smolted as yearlings in April-May (Matthews and Waples 1991).

Although spring Chinook salmon smolt as yearlings, in-basin migrations as fry or parr are not uncommon. Fry dispersal was well documented in the Selway River during studies of Chinook salmon reintroductions (Cramer 1995). A second downstream migration of spring Chinook salmon in the upper portion of the rearing areas occurs in the fall as juveniles seek suitable winter habitat (Hesse et al. 1995; Walters et al. 2001).

Little is known about the distribution of Snake River spring Chinook salmon in the ocean because few are ever caught in ocean fisheries. Analyses of coded-wire tag (CWT) recoveries from Snake River spring Chinook salmon during the intensive ocean fisheries of the 1980s indicated that harvest rate of these fish in the ocean was less than 1% (Berkson 1991).

Distribution of spring Chinook salmon to the North Fork Clearwater River is blocked by , and with the exception of the mainstem migration corridor, they are absent from the Lower Clearwater. The current distribution of spring Chinook salmon within the Clearwater

Page 19

subbasin includes the Lolo Creek drainage and all major drainages above the confluence of the Middle and South Forks of the Clearwater River. Relatively contiguous distributions of spring/summer Chinook salmon exist in the Lolo/Middle Fork, South Fork, and Upper and Lower Selway. Spring/summer Chinook salmon are absent from many tributaries in the Lochsa River drainage, but found in Pete King and Fish Creeks, and most tributaries above (and including) Warm Springs Creek.

Spring Chinook salmon are classified as “present – depressed” in all areas of the Clearwater subbasin where status information is available. Aerial surveys of spring Chinook salmon redds in the Clearwater subbasin have been conducted since 1966. Data has been collected from established reaches on an annual basis in both natural production areas as well as areas where production is regularly influenced by hatchery releases of Chinook salmon.

Adult Run Timing - Run timing of natural-origin adults returning to the Powell and South Fork Clearwater traps generally occurs between late May and early September and resembles a bimodal distribution that is heavily skewed toward the first mode. The dates at which the 25th, 50th, and 75th percentiles of adults returning to the traps are displayed in Table 5 below.

Adult Age Structure – Spring- and summer-run Chinook salmon in the Snake River ESU are comprised of four age classes (1, 2, 3, and 4 ocean) with the majority returning after two or three years in the ocean (Table 6). Using dorsal fin ray aging techniques, Keifer et al (2002, 2004) and Copeland et al. (2008) estimated the ocean age proportions of natural-origin spring/summer run

Page 22

Chinook salmon passing upstream of Lower Granite Dam from 2002 through 2007. They found that, while age structure was variable from year to year, the majority of returning adults were composed of two-ocean adults.

Ages of natural-origin Chinook salmon returning to the Clearwater n River weir are determined based on length frequency and consist of three age classes (1, 2, and 3 ocean). While it is likely that a few four-ocean adults return to the Clearwater River, overlapping length frequencies of three- and four-ocean adults precludes being able to distinguish the two age classes based on length frequency alone. Age class structure of natural-origin adults returning to the Powell, Crooked River and Red River satellite facilities from 1998-2008 are displayed in tables 7, 8, and 9 below.

The majority of adult returns are in the 70-90 cm size class but vary depending on year class strength. Typically, one-ocean adults are less than 63cm fork length, two-ocean fish are 63-85 cm and three-ocean fish are greater than 85 cm (IDFG, unpublished data).

The trap is typically operated from March through October, so fish emigrating between November and February are not accounted for. Also, for most years, the trap is not operated for a one to three week period during spring high flows in May and June. Trapping data from the South Fork Clearwater River (Red and Crooked River) shows a similar pattern.

Regardless of when juveniles emigrate from the spawning areas in the Clearwater River, they rear in fresh water for one full year after emergence and subsequently migrate to the ocean as yearling smolts from April through June. Table 16 below shows the seaward migration timing of natural-origin Chinook salmon from Crooked Fork Creek and Red River based on PIT-tag interrogation data from Lower Granite Dam for brood years 1997-2007. Fish were PIT-tagged as both subyearling parr and pre-smolts and as yearling smolts. Juveniles PIT-tagged as subyearlings typically arrive at Lower Granite Dam three to four weeks prior to juveniles tagged as yearling smolts (Table 16).

Hatchery Programmatic Maintenance Activities at Satellite Facilities

The rivers that supply water to each satellite facility, (Red River, upper and lower Crooked River and Powell), flow through a valley which is heavily influenced by logging and or historic mining activity. The rivers transport and deposit a great deal of sediment which can hamper normal hatchery operation. As such, in-river maintenance of the hatchery diversion dams and intake structures, intake piping, adult fish weir and fish ladder is a common requirement. A description of each maintenance task follows.

Satellite facility diversion dam and water source intake: The various wooden, steel and concrete structures which constitute the diversion dams and water source intakes at both the upper and lower Crooked River facilities, Red River and Powell sites may become compromised simply from age and exposure to changing weather conditions. Hatchery personnel must periodically complete a visual inspection of the structures by entering the river channel with hip boots or waders or dry suits with supplied air systems. Minor repairs such as stop-log replacement or rebuilding of cobble diversion weir at Red River may be completed in place by workers using hand tools, while more extensive repairs may require portions of these structures to be temporarily removed for repair or replacement. Should removal of these structures be necessary, a backhoe/trackhoe or a crane or similar lifting device operated from the stream bank would be employed. Heavy equipment will not enter the stream channel. In some instances it may be necessary to construct a small cofferdam to isolate the work area from the river to facilitate repair work. Cofferdams would be constructed from sheet piling or ecology blocks lined with heavy mil plastic sheeting, thereby reducing the potential for sediment to escape and be transported downstream. Should isolation of the work area with coffer dams also involve dewatering, hatchery personnel would electrofish the site to capture and relocate any listed species present within the coffered work zone

Throughout the year, gravel, sediment and small woody debris is deposited in the vicinity of the Satellite Facility diversion dams and water supply intake structures at both the upper and lower Crooked River and Red River and Powell sites. The accumulation of sediment and debris has the potential to restrict the volume of water that can be diverted to the hatchery. Materials must be removed annually to ensure an uninterrupted supply of water for fish culture and trapping operation. The diversion dams and water source intake structures may become damaged by the seasonal movement and deposition of sediment and large woody debris. These structures may Page 31

need to be temporarily removed for repair or replacement.

Removal of accumulated sediment or woody debris may be accomplished using a variety of techniques ranging from a clam shell type excavation bucket mounted to a crane, to a tracked or rubber tired excavator. In all cases, excavation equipment will not enter the stream channel. Access within the wetted perimeter of the stream will be limited to workers using hand tools, mud and sand suction dredges or guiding the operation of the heavy equipment. In some instances it may be desirable to construct small cofferdams using ecology blocks lined with heavy mil plastic sheeting to isolate the work area from the river channel.

The diversion dams and water source intakes are located within the migration and spawning habitat of ESA listed steelhead and Bull Trout. Direct effects to individual adult or juvenile Bull Trout and steelhead are a concern during all in-river maintenance activities. Effects could include disturbance and displacement of fish as a result of personnel or heavy equipment working near the river channel. A small sediment plume will likely be created as a result of substrate disturbance. This plume will persist for a short distance downstream and could affect embryonic life stages of Chinook salmon and steelhead or Bull Trout. To minimize impacts to incubating Chinook salmon, steelhead or Bull Trout, all work will be completed within a work window of July 1 (post-steelhead fry emergence) to August 15 (pre-Chinook salmon spawning) previously established by NOAA Fisheries for similar construction projects within the vicinity of Satellite Facilities. All excavated material will be removed from the river and loaded into a truck for offsite disposal or spread evenly along the river bank or used as local dirt parking lot fill.

Adult fish weir: Following periods of high flow, sand and gravel accumulates in front of the adult fish weir and entrance to the fish ladder and trap used for capturing adult spring and summer Chinook salmon and steelhead returning to the hatchery. This gravel accumulation restricts river flow and may encourage bank erosion, resulting in further sedimentation or damage to hatchery structures and equipment.

Removal of accumulated sediment or woody debris may be accomplished using a variety of techniques ranging from a clamshell type excavation bucket mounted to a crane, to a tracked or rubber tired excavator or workers operating mud and sand suction dredges. In all cases, excavation equipment will not enter the stream channel suction dredges will be mounted on floating devices. Access within the wetted perimeter of the stream will be limited to workers guiding the operation of the crane or excavator or workers operating mud and sand suction dredges. Excavated material will be loaded into a truck and hauled off site for disposal or spread evenly along the river bank or used as local dirt parking lot fill.. A small, short duration, sediment plume is anticipated during the excavation process. The adult fish trap and fish ladder is located within the migration corridor of spring Chinook salmon, steelhead and bull trout.

Aside from damages or loss of functionality related to high water events, the integrity of the adult weir may be compromised simply by age and exposure to changing weather conditions. Hatchery personnel must periodically complete a visual inspection of the structures by entering the river channel with hip boots, waders or dry suits with supplied air systems. Minor repairs may be completed in place by workers using hand tools, while more extensive repairs may require individual weir panels to be temporarily removed for repair or replacement. Should removal of these structures exceed the lifting capability of hatchery personnel, a crane or similar device operated from the stream bank would be employed. Heavy equipment will not enter the Page 32

stream channel. In some instances it may be necessary to construct a small cofferdam to isolate the work area from the river to facilitate repair work. Cofferdams would be constructed from sheet piling or ecology blocks lined with heavy mil plastic sheeting, thereby reducing the potential for sediment to escape and be transported downstream. Should isolation of the work area with coffer dams also involve dewatering, hatchery personnel would electrofish the site to capture and relocate any listed species present within the coffered work zone

Direct effects to individual adult or juvenile spring or summer Chinook salmon, steelhead and bull trout are a concern during these maintenance activities. Effects could include disturbance and displacement of fish as a result of personnel or heavy equipment working near the river channel. To minimize potential impacts to embryonic life stages of Chinook salmon or steelhead, all work will be completed within a work window of July 1 (post steelhead fry emergence) to August 15 (pre Chinook salmon spawning) previously established by NOAA Fisheries for similar construction projects within the vicinity. No machinery is placed in the river channel thus eliminating any risk of fuel or oil contamination. The removal of materials as described herein may occur as frequently as once each year depending upon the magnitude of spring runoff.

River bank stabilization: While infrequent, extreme high runoff events have the potential to erode the stream bank in the vicinity of the satellite facilities, causing localized flooding, damage to hatchery buildings or the interruption of water supplied to the facilities. To respond to threats of this nature it may be necessary to place fill material or rip rap within the river channel to control bank erosion. All materials used in such efforts would be clean (washed) rock to limit the introduction of sediment to the river channel. Machinery used for rock placement would be operated from outside the wetted perimeter of the stream to avoid the possibility of fuel or oil entering the water. Direct effects to individual adult or juvenile spring Chinook salmon, steelhead and bull trout are a concern during these maintenance activities. Effects could include disturbance and displacement of fish as a result of personnel or heavy equipment working near the river channel. At certain times of year impacts to embryonic life stages resulting from stream bank stabilization activities are also a concern; however, considering that such stabilizations activities would likely be done in response to extreme high river flows and localized flooding, the turbidity generated from the action would likely be less than what is already present in the river.

Programmatic Maintenance at the main Clearwater Fish Hatchery

The Clearwater Fish Hatchery receives water through two supply pipelines from Dworshak Reservoir. The warm water or surface intake is attached to a floating platform and can be adjusted from five feet to forty feet below the surface. The cool water intake is stationary at 245 feet below the top of the dam. When water temperatures drop in the fall, the surface intake is moved to the warmest water available until water temperatures rise in the spring. All water is gravity fed to the hatchery. The intake screens are in compliance with NMFS screen criteria by design of the Army Corp of Engineers. Floating debris and algae plug the intake screens and throughout the year small woody debris is deposited in the vicinity of the water supply intake structures at both the upper and lower level intake screens. The accumulation of debris has the potential to restrict the volume of water that can be diverted to the hatchery. Materials must be removed from the surface screen annually and the deep water screen intermittently to ensure an uninterrupted supply of water for fish culture operation.

Page 33

Removal of accumulated woody debris and algae and inspections of screens and piping may only be accomplished using a dive contractor certified and approved through Army Corps of Engineers security clearance protocol. Annually water supply intakes and supply pipelines will be temporarily shut down and emergency closure valves will be exercised inside the dam and at the hydropower plant. Both pipelines cross under the riverbed of the North Fork of the Clearwater River just upstream of the state Highway 7 bridge en route to the main hatchery. In the occasion of a pipeline maintenance event a coffer dam would be built parallel to the buried pipelines to accommodate heavy equipment to excavate and expose the pipeline construction/maintenance in accordance with Corps of Engineers guidelines as used with original construction.

Provide information regarding past takes associated with the hatchery program, (if known) including numbers taken, and observed injury or mortality levels for listed fish. No take of ESA-listed salmon or steelhead has been documented or is anticipated.

Provide projected annual take levels for listed fish by life stage (juvenile and adult) quantified (to the extent feasible) by the type of take resulting from the hatchery program (e.g. capture, handling, tagging, injury, or lethal take). No take from hatchery operations (adult trapping and broodstock collection) is anticipated. Estimated take by activity for hatchery programmatic maintenance and research/monitoring are provided in Appendix A; Tables 1a and 1b respectively. Take for juvenile trapping is covered under an annually renewed 4d Research permit for the Idaho Chinook Supplementation Study (2010- 14706).

Indicate contingency plans for addressing situations where take levels within a given year have exceeded, or are projected to exceed, take levels described in this plan for the program. We have not experienced any significant mortality of ESA-listed adult steelhead in conjunction with our maintenance activities at the satellite facilities. However, in the unlikely event that unforeseen conditions cause mortality of ESA-listed steelhead adults, maintenance activities will be immediately altered to eliminate the cause of the mortality. If necessary, activities will be suspended until corrections are completed.

3.3 RELATIONSHIP TO HARVEST OBJECTIVES

The Lower Snake River Compensation Plan defined replacement of adults “in place” and “in kind” for appropriate state management purposes. Juvenile production and adult escapement targets were established at the outset of the LSRCP. The Hells Canyon Settlement Agreement defined mitigation goals in terms of smolts released. State and Tribal co-managers have established near and long term expectations for adult returns to Idaho Power facilities based on the smolt to adult return rates used to size the production capacity of the LSRCP hatcheries. State, tribal and federal co-managers work co-operatively to develop annual production and mark plans that are consistent with original LSRCP and Hells Canyon Settlement Agreement, the US vs. OR Management Agreement, and recommendations of the HSRG and HRT relative to ESA impact constraints, genetics, fish health and fish culture concerns.

In the Snake River basin, mitigation hatchery returns are harvested in both mainstem and tributary terminal fisheries. Fish that return in excess to broodstock needs for the hatchery programs are shared equally between sport and Tribal fisheries. State and Tribal co-managers cooperatively manage fisheries to maximize harvest of hatchery returns that are in excess of broodstock needs. Fisheries are managed temporally and spatially to: minimize impacts to non- target natural returns and comply with ESA incidental take limits; achieve hatchery broodstock goals; achieve sharing objectives among Tribal and recreational fisheries; optimize the quantity and quality of fish harvested that are in excess of what is needed to meet broodstock needs; maximize temporal and spatial extent of fishing opportunities; and minimize conflicts between different gear types and user groups

State and Tribal co-managers confer pre-season relative to assessing forecasted levels of abundance of both hatchery and natural fish in the fisheries. Forecasts are used to project likely non-tribal and tribal harvest shares. Incidental take rates applicable to fisheries are projected

Page 35

based on forecasted natural populations addressed in the 2000 Biological Opinion. As part of the in-season harvest management and monitoring program, the IDFG and Tribal cooperators conduct annual angler surveys to assess the contribution program fish make toward meeting program harvest mitigation objectives. The surveys are also used for in-season assessments of recreational and Tribal harvest shares and to determine ESA take relative to allowable levels based on the sliding scales of natural spawner abundance. In-season, state, tribal, and federal co- managers conduct weekly teleconferences in concert with web-based data sharing tools to confer about harvest and incidental take levels and the disposition of fish captured at the hatchery traps in excess of broodstock needs. Co-managers also conduct meetings after fisheries conclude to assess the success of the management actions taken during the season. 3.3.1 Describe fisheries benefiting from the program, and indicate harvest levels and rates for program-origin fish for the last twelve years, if available.

The Clearwater River Basin salmon fishery targets hatchery fish produced by Dworshak National Fish Hatchery, Kooskia National Fish Hatchery, Nez Perce Tribal Hatchery, and the Clearwater Fish Hatchery and its satellites. When fishing seasons are held, the following areas are typically open: 1) mainstem Clearwater River, 2) North Fork Clearwater River, 3) South Fork Clearwater River, and 4) Lochsa River.

Harvest data for 1997-2007 is displayed in Table 17 below. These estimates do not include harvest downstream of Idaho.

3.4 RELATIONSHIP TO HABITAT PROTECTION AND RECOVERY STRATEGIES

Hatchery production for harvest mitigation is influenced but not specifically linked to habitat protection strategies in the Clearwater basin and other areas. The NMFS has not developed a

Page 36

recovery plan specific to Snake River Chinook salmon, but the Clearwater program is operated consistent with existing Biological Opinions.

3.5 ECOLOGICAL INTERACTIONS

The possibility of collecting ESA-listed salmon or steelhead during broodstock collection in upper Clearwater River tributaries is remote. Fall Chinook and sockeye salmon adults are temporally and spatially separated from broodstock collection at the Clearwater Fish Hatchery satellite weirs. Several studies have shown Chinook to have a high degree of fidelity to natal stream or release site (Bowles and Leitzinger 1991). The satellite weirs are over 100 miles from the mouth of the Clearwater River. We cannot differentiate spring Chinook naturally produced in the upper Clearwater drainage from listed spring/summer Chinook. We have no indication that marked hatchery fish from even the same geographic area as listed Chinook salmon (such as McCall summer Chinook) are being collected in the upper Clearwater River. We conclude there would is no effect to listed salmon from our adult spring Chinook broodstock collection at the Clearwater Fish Hatchery satellite weirs.

In addition to broodstock collection, adults may be out-planted from a satellite weir site to spawning areas upstream for research or supplementation. Adult out-plants will not exceed estimated carrying capacity of rearing habitat for their progeny, so we conclude there would be no effect to listed salmon from this action.

The LSRCP "Hatchery Evaluation Study Program" in the Clearwater River will continue studies initiated to determine hatchery rearing and release strategies that will help meet the mitigation requirements of the LSRCP program and the management goals of the IDFG. Within this goal, the hatchery program will attempt to improve the survival of hatchery fish while avoiding negative effects to natural populations. Two primary objectives are central to achieving this goal: 1) evaluate the success of the LSRCP program in meeting specified goals and 2) identify factors limiting hatchery success and recommend possible improvements based on existing knowledge and experimentation. Hatchery operation studies have focused on the monitoring and evaluation of hatchery loading and size variables, timing of release studies, location of release studies, and natural rearing studies.

Angler surveys will continue to assess the LSRCP contribution to Idaho's steelhead and Chinook fisheries, estimate the total escapement of LSRCP fish, recover information on marked fish, and obtain data for managing fisheries while protecting wild stocks. We do not believe that any of these ongoing studies adversely affect listed salmon or steelhead species.

The physical operation of the Clearwater Fish Hatchery and its satellites is expected to have no affect on listed salmon or steelhead. All effluents must meet existing water quality standards. Water sources are properly screened and maintained so as to not affect listed salmon or steelhead.

Hatchery spring Chinook salmon from the Clearwater Fish Hatchery program enter the Snake River emigration corridor at Lower Granite Reservoir. Their presence in the reservoir overlaps to some degree with listed sockeye, spring/summer Chinook salmon, and steelhead. We believe Chinook from the program are temporally separated from listed fall Chinook salmon in the reservoir based on different migration periods.

Page 37

Our current hatchery practices include measures to control pathogens. Bacterial Kidney Disease (BKD) continues to persist in hatcheries, but it is also endemic in naturally spawning populations. Efforts to minimize BKD incidence in hatcheries, such as adult disease testing, culling, and single family incubation, will continue. There is no evidence that horizontal transmission of disease from the Clearwater Fish Hatchery program to listed species occurs or has a measurable effect on listed species survival and recovery.

We conclude that the LSRCP spring Chinook program in the upper Clearwater River is not likely to jeopardize the continued existence or the recovery of listed spring/summer Chinook salmon, sockeye salmon, fall Chinook salmon or steelhead.

There is no effect from the Clearwater Fish Hatchery program to listed spring/summer Chinook salmon in their production area. We believe that even with low abundance of listed Chinook salmon, the potential of affecting them with the Clearwater Fish Hatchery program by straying of adults, disease transmission, or competitive effects in the migration corridor, is remote.

Fall Chinook salmon are temporally and spatially separated from the LSRCP spring Chinook salmon release and should not be adversely affected.

Sockeye are spatially separated from the LSRCP spring Chinook salmon release until they enter Lower Granite Reservoir. It appears that there is also some temporal separation of migration timing. Most of the hatchery fish have probably passed through Lower Granite Reservoir by the time sockeye arrive, in years of normal water conditions.

SECTION 4. WATER SOURCE

4.1 PROVIDE A QUANTITATIVE AND NARRATIVE DESCRIPTION OF THE WATER SOURCE (SPRING, WELL, SURFACE), WATER QUALITY PROFILE, AND NATURAL LIMITATIONS TO PRODUCTION ATTRIBUTABLE TO THE WATER SOURCE

Clearwater Fish Hatchery - The Clearwater Fish Hatchery receives water through two supply pipelines from Dworshak Reservoir. The warm water intake is attached to a floating platform and can be adjusted from five feet to forty feet below the surface. The cool water intake is stationary at 245 feet below the top of the dam. An estimated 10 cfs is provided by the cool water supply and 70 cfs is provided from the warm water supply. The cool water supply has remained fairly constant between 38°F and 45°F. The warm water can reach 80°F but is adjusted regularly to maintain 56°F for as long as possible throughout the year. When water temperatures drop in the fall, the intake is moved to the warmest water available until water temperatures rise in the spring. All water is gravity fed to the hatchery. The intake screens are in compliance with NMFS screen criteria by design of the Army Corp of Engineers.

Red River Satellite - Red River’s water source is from the South Fork of Red River where a

Page 38

hand built diversion diverts water into a screen on the bottom of the river and a pipeline delivers it to the rearing pond and adult facility. The intake screens are in compliance with NMFS screen criteria by design of the Army Corp of Engineers.

Crooked River Satellite - Crooked River’s water source is from Crooked River where a concrete weir with dam board slot is used to control water level at the facility. The intake screens are in compliance with NMFS screen criteria by design of the Army Corp of Engineers.

Powell Satellite – The water source is from Walton Creek where a concrete weir structure with sheet pilings and vertical screens diverts water to the rearing pond and adult facility. The intake screens are in compliance with NMFS screen criteria by design of the Army Corp of Engineers.

4.2 INDICATE RISK AVERSION MEASURES THAT WILL BE APPLIED TO MINIMIZE THE LIKELIHOOD FOR THE TAKE OF LISTED NATURAL FISH AS A RESULT OF HATCHERY WATER WITHDRAWAL, SCREENING, OR EFFLUENT DISCHARGE

The intake screens comply with NMFS screen criteria and were designed by the Army Corp of Engineers.

5.4 INCUBATION FACILITIES

The Clearwater Hatchery incubation room contains 49 double-stack Heath incubators with a total of 784 trays available for egg incubation. The upper and lower halves of each stack (eight trays each) have a different water supply and drain. This design aids in segregation of diseased eggs. The maximum capacity of this facility is five million green eggs. The incubation room is supplied with both reservoir water sources to provide the desired temperature for incubation at a flow of 5 to 8 gallons per minute (gpm) per one-half stack.

Isolation incubation consists of 16 double-stack Heath incubators with a total of 256 trays available for egg incubation. The maximum capacity of this facility is 1.5 million green eggs. The isolation incubation room is supplied with both reservoir water sources to provide the desired temperature for incubation with a flow of 5 to 8 gpm per stack.

5.5 REARING FACILITIES

Clearwater Fish Hatchery - Chinook salmon raceways are 200 feet x 10 feet x 3 feet deep. Eleven raceways have a total rearing space of 66,000 cubic feet. The raceways are supplied with water from both primary and secondary intakes and a mixing chamber, which allows for the control of water temperature. The designed rearing capacity of these raceways is 1.5 million smolts at a 0.3 density index (DI). The estimated flow per raceway is 2.4 cfs. Additional rearing

Page 40

space is available in the steelhead raceway structure.

Early rearing space consists of 60 concrete vats. Each vat measures 40 feet x 4 feet x 3 feet deep and contain 480 cubic feet of rearing space. This part of the facility can rear 5.9 million fish to 287 fish/lb. at a 0.3 DI. The vats are supplied with water from each reservoir intake and have a flow of approximately 120 gpm per vat when all vats are in use. An incubation jar is plumbed directly into each vat. The 60 incubator jars have a total capacity of 2.6 million eggs with a flow of 15 gpm per jar.

Crooked River - The Crooked River facility has two raceways, measuring 145 feet x 20 feet x 4 feet deep, for a total of 23,200 cubic feet. These raceways have a capacity of 700,000 juveniles at a DI of 0.29. Water flow per raceway is 6 cfs. Each raceway is outfitted with three automated Nielson feeders.

Red River – The Red River facility has one 170 foot x 70 foot x 4 foot-6 in. deep rearing pond with a maximum capacity of 320,000 juveniles at a DI of less than 0.3 and a maximum capacity of 500,000 smolts at a DI of 0.092. Maximum water flow through this pond is 6.24 cfs. This pond has a hypalon plastic liner with cobblestones placed on the inclined banks to hold the liner in place. The bottom of the pond is bare, which aids in pond vacuuming. A catwalk runs the entire length of the rearing pond and holds eight automated Nielson feeders. .

Powell - The rearing pond measures 165 feet x 65 feet x 5 feet deep and has 53,625 cubic feet of rearing space. The normal loading rate of 320,000 fish equates to a DI significantly less than 0.3. The maximum design capacity is 500,000 fish with a DI of 0.092. Water flow through this pond is 6.24 cfs. A catwalk across the length of the pond supports eight automated Nielson feeders.

5.6 ACCLIMATION/RELEASE FACILITIES

Same as described in Section 5.5 above.

5.7 DESCRIBE OPERATIONAL DIFFICULTIES OR DISASTERS THAT LED TO SIGNIFICANT FISH MORTALITY

Infrequent but significant fish mortality has occurred at the Crooked River and Powell satellites when water intake systems become obstructed with debris and slush ice during periods of high water discharge and low air temperatures during spring acclimation.

5.8 INDICATE AVAILABLE BACK-UP SYSTEMS AND RISK AVERSION MEASURES THAT WILL BE APPLIED THAT MINIMIZE THE LIKELIHOOD FOR THE TAKE OF LISTED NATURAL FISH THAT MAY RESULT FROM EQUIPMENT FAILURE, WATER LOSS, FLOODING, DISEASE TRANSMISSION, OR OTHER EVENTS THAT COULD LEAD TO INJURY OR MORTALITY.

Clearwater Fish Hatchery - An alarm system monitors for low water in each rearing area and

Page 41

high water temperature on the warm water supply. Hatchery staff checks raceway flows and temperatures manually on a daily schedule.

Red River – A low water alarm system is installed in the adult holding and acclimation/rearing ponds. A rigorous screen cleaning schedule has been implemented to insure that screens stay clear of debris during periods of high discharge.

Crooked River - A low water alarm system is installed in the juvenile rearing raceway. Living quarters have recently been built on station to house staff. Staff monitors intake screens day and night during spring acclimation. When nightly air temperatures drop to 29˚C, screens are cleaned as often as necessary to maintain constant flow of water to raceway.

Powell – An alarm system is in place to detect low water resulting from an obstructed water intake. A rigorous screen cleaning schedule has been implemented to insure that screens stay clear of debris during periods of high discharge. When nightly air temperatures drop below 29˚C, screens are cleaned as often as necessary to maintain constant flow of water to the rearing pond.

SECTION 6. BROODSTOCK ORIGIN AND IDENTITY

This section describes the origin and identity of broodstock used in the program, its ESA-listing status, annual collection goals, and relationship to wild fish of the same species/population.

6.1 SOURCE

Founding hatchery stocks used for spring Chinook salmon reintroductions were primarily obtained from the Rapid River Hatchery (Kiefer et al. 1992; Nez Perce Tribe and Idaho Department of Fish and Game 1990). Initially however, spring Chinook stocks imported for restoration came from Carson, Big White, Little White or other spring Chinook captured at Bonneville Dam (Nez Perce Tribe and Idaho Department of Fish and Game 1990). Genetic analyses confirm that existing natural spring Chinook salmon in the Clearwater River subbasin are derived from reintroduced Snake River stocks (Matthews and Waples 1991).

6.2 SUPPORTING INFORMATION

6.2.1 History

Red River – The Red River pond was built in 1977 under the Columbia River Fisheries Development Project and was administered by NMFS, IDFG, USFS, and the Pacific Northwest Regional Commission until 1986. In 1986, a permanent adult trapping facility and holding complex was constructed by the Army Corps of Engineers as part of the LSRCP. Between 1977 and 1980 and in 1983 and 1987, and between 1990 and 1994, Rapid River stock spring Chinook fingerlings were released at the Red River satellite (Bowles and Leitzinger 1991). Carson National Fish Hatchery fingerlings were released in 1981. From 1982 through 1985, only adults returning to the Red River satellite were used to source eggs for broodstocks. However, Dworshak National Fish Hatchery supplied juveniles for the 1988 release when Red River fish had to be destroyed due to the presence of Infectious Pancreatic Necrosis Virus (IPN). In 1987

Page 42

and from 1989 through 1992, Red River stock smolts reared at Kooskia and Dworshak National Fish hatcheries were released at the Red River facility. Since 1997, Red River and Crooked River stocks have generally been treated as one stock with respect to broodstock management.

Crooked River – The Crooked River satellite has been in operation as part of the LSRCP since 1990. Juvenile Chinook salmon produced at Rapid River Hatchery and at Dworshak National Fish Hatchery were released at this location in 1989. Juvenile Chinook salmon were released from Kooskia National Fish Hatchery in 1990 and 1991 (Bowles and Leitzinger 1991). Eyed- eggs received in 1994 from Rapid River/Looking Glass hatchery stock were also incorporated into the program. In 1995, all fish released at the Crooked River facility originated from Rapid River stock. In 1996 and 1998, only Crooked River adults were used to develop broodstocks. Since 1997, Red River and Crooked River stocks have been treated as one stock with respect to broodstock management.

Powell – The founding broodstock for the Powell satellite was sourced from the Lochsa River at the confluence of Colt Killed Creek and Crooked Fork Creek. Kooskia and Dworshak National Fish hatcheries provided juveniles for release between 1989 and 1991. In 1999, juveniles produced from Rapid River stock were released from the Powell satellite.

6.2.2 Annual size

No ESA-listed spring Chinook salmon are trapped as part of this program and no natural-origin Chinook salmon are used for broodstock. Annual guidelines for broodstock size are listed below. As the Nez Perce Tribal Hatchery comes on line in the near future, production associated with this program that is currently being accommodated by the Clearwater Fish Hatchery will become a tribal responsibility at their new facility.

The current spring/summer Chinook salmon program at the Clearwater Hatchery includes the release of 2,635,000 spring-run Chinook salmon and 200,000 summer-run Chinook salmon. Managers intend to increase the summer run component over time to one million yearling smolts. To achieve the current release goals, approximately 980 spring-run and 60 summer-run females are collected for broodstock along with a similar number of males to achieve a 1:1 spawn ratio. Additionally, IDFG provides eggs up to 200 females to the Nez Perce Tribe for programs operated out of the Nez Perce Tribal Hatchery.

South Fork Clearwater River Program – Red River and Crooked River traps (IDFG mitigation program):

Approximate adult spawn target: 500 females (approximately 2.026 million green eggs)

South Fork Clearwater River Program – Red River and Crooked River traps (Nez Perce Tribal supplementation program):

The NPT requests eggs from up to 200 females

Lochsa River Program – Powell trap (IDFG mitigation program):

Approximate adult spawn target: 483 females (approximately 1.94 million eggs)

Page 43

6.2.3 Past and proposed level of natural fish in broodstock

See Section 6.2.1 above. No ESA-listed or endemic fish were used to source the Clearwater Fish Hatchery spring Chinook salmon program. Natural stocks were extirpated by Lewiston Dam.

6.2.4 Genetic or ecological differences

The Clearwater Fish Hatchery spring Chinook salmon program will have no genetic or ecological effect on endemic stocks. Genetic analyses confirm that existing natural spring Chinook salmon in the Clearwater River subbasin are derived from reintroduced Snake River stocks (Matthews and Waples 1991).

Genetic analyses using 13 microsatellite loci have indicated that Snake River Chinook salmon exhibit structuring within subbasins (including the Clearwater), meaning the populations within a subbasin are genetically differentiated as a result of strong philopatry (Narum et al. 2007). However, populations within a subbasin generally cluster together, independent from other subbasins (Narum et al. 2007). The exceptions involve wild and hatchery stock comparisons. For example, Narum et al. (2007) observed that all of the stream-type collections from the Clearwater River (hatchery and wild) cluster tightly with samples from the Rapid River Hatchery, and the collections of natural ocean types from the Clearwater River (three temporal replicates combined) were not significantly different from either Lyons Ferry Hatchery or the Nez Perce Tribal Hatchery. Populations in subbasins that have not received large numbers of out of basin hatchery stocking (e.g. M.F. Salmon River, S.F. Salmon River) appear genetically distinct and do not cluster with hatchery stocks. Narum et al. (2007) found no evidence that re- established Chinook salmon populations in the Clearwater River subbasin were genetically bottlenecked, nor that they exhibit any unique remnant genetic variation.

6.2.5 Reasons for choosing

Endemic spring Chinook salmon stocks in the Clearwater River basin were extirpated by Lewiston Dam (1927 to 1972). As such, an endemic broodstock could not be used to found this program.

6.3 INDICATE RISK AVERSION MEASURES THAT WILL BE APPLIED TO MINIMIZE THE LIKELIHOOD FOR ADVERSE GENETIC OR ECOLOGICAL EFFECTS TO LISTED NATURAL FISH THAT MAY OCCUR AS A RESULT OF BROODSTOCK SELECTION PRACTICES.

No adverse impacts or effects to the listed population are expected as wild/natural adults are not currently trapped and used for broodstock purposes.

Page 44

SECTION 7. BROODSTOCK COLLECTION

7.1 LIFE-HISTORY STAGE TO BE COLLECTED (ADULTS, EGGS, OR JUVENILES)

All broodstock collected for this program come from hatchery-origin adults.

7.2 COLLECTION OR SAMPLING DESIGN

At this time no unmarked (natural origin) fish are incorporated into the hatchery broodstock. All adult fish collected for broodstock at all locations are of hatchery origin. Fish are selected randomly from ripe fish during weekly spawning events.

Red River - Collection is accomplished by a weir across Red River, diverting fish into the trapping facility.

Crooked River - Collection is accomplished by a weir across Crooked River, diverting fish into the trapping facility.

Powell - The fish encounter no weir on the Lochsa River and turn into the attraction water of Walton Creek where they were acclimated and released as smolts.

7.3 IDENTITY

All harvest mitigation hatchery-produced fish are marked with an adipose fin clip. Releases for supplementation programs may be marked with a pelvic fin clip or CWT and no fin clip.

7.4 PROPOSED NUMBER TO BE COLLECTED

7.4.1 Program goal (assuming 1:1 sex ratio for adults)

No ESA-listed spring Chinook salmon are trapped as part of this program. Annual guidelines for broodstock size are listed below. The current spring/summer Chinook salmon program at the Clearwater Hatchery includes the release of 2,635,000 spring run Chinook salmon and 200,000 summer run Chinook salmon. To achieve these release goals, approximately 980 spring run and 60 summer run females are collected for broodstock along with a similar number of males to achieve a 1:1 spawn ratio. Additionally, IDFG provides eggs from up to 200 females to the Nez Perce Tribe for other programs operated in the Clearwater River drainage.

South Fork Clearwater River Program – Red River and Crooked River traps (IDFG mitigation program):8

Approximate adult spawn target: 500 females (approximately 2.026 million green eggs)

Adults may be released for natural spawning or recycled in the sport fishery. 2 Release numbers may include juveniles received as eyed-eggs from other facilities.

7.5 DISPOSITION OF HATCHERY-ORIGIN FISH COLLECTED IN SURPLUS OF BROODSTOCK NEEDS

Crooked River and Red River – In the past, hatchery-origin adults that were part of a supplementation experiment were passed above weirs to spawn naturally. Currently, only natural-origin returns are passed above the weirs. General production fish that return in excess of broodstock needs are recycled through the sport fishery or out-planted according to management agreements.

Powell – In the past, hatchery-origin adults that were part of a supplementation experiment were

Page 46

passed above weirs to spawn naturally. Currently, only natural-origin returns are passed above the weirs. General production fish that return in excess of broodstock needs are recycled through the sport fishery or are out-planted according to management agreements.

7.6 FISH TRANSPORTATION AND HOLDING METHODS

Adult spring Chinook salmon trapped at Crooked River are transported daily to the Red River satellite holding facility. All fish trapped at Red River and Crooked River are transferred to the main Clearwater Fish Hatchery for final holding and spawning. At the time of transfer, fish are measured, injected with Erythromycin (20 mg/kg), inspected for injuries, and scanned for CWT, PIT, and radio tags. Fish are transferred using adult transport vehicles.

Pre-spawn adults are held in adult holding facilities described above. Fish receive routine treatments with formalin (125 ppm) to control the spread of fungus.

7.7 DESCRIBE FISH HEALTH MAINTENANCE AND SANITATION PROCEDURES APPLIED

Fish receive routine treatments with formalin (125 ppm) to control the spread of fungus. At spawning, eggs from females exhibiting gross clinical signs of bacterial kidney disease may be culled. Tissue is sampled from each spawned female and analyzed for viral pathogens and for the causative agent responsible for bacterial kidney disease.

7.8 DISPOSITION OF CARCASSES

All pre-spawning mortality fish are disposed of in a sanitary landfill. Carcasses generated by spawning activities may be returned to upper tributaries for stream nutrient enhancement. All carcasses that exhibit gross clinical signs of bacterial kidney disease are disposed of in a landfill.

7.9 INDICATE RISK AVERSION MEASURES THAT WILL BE APPLIED TO MINIMIZE THE LIKELIHOOD FOR ADVERSE GENETIC OR ECOLOGICAL EFFECTS TO LISTED NATURAL FISH RESULTING FROM THE BROODSTOCK COLLECTION PROGRAM

Only hatchery-origin, non ESA-listed adults are collected for broodstock purposes.

SECTION 8. MATING

This section describes fish mating procedures that are used, including those applied to meet performance indicators identified previously.

8.1 SELECTION METHOD

Female spring Chinook salmon are sorted two times per week. Generally, two spawn days occur each week. Males are randomly selected for spawning on each spawning day.

Page 47

As each male is spawned, it receives an opercle punch and is placed back into the holding pond. Males are generally not used more than two times. Every effort is made to use all returning fish for spawning during the spawning year. At least five to ten percent of the males used for spawning will be composed of jacks.

8.2 MALES

See Section 8.1.

8.3 FERTILIZATION

Spawning ratios of 1 male to 1 female will be used when the broodstock population contains more than 100 females. If the spawning population contains between 50 and 100 females, then eggs from each female are split into two equal sub-families. Each sub-family is fertilized by a different male. One cup of well water is added to each bucket and set aside for 30 seconds to one minute. The two buckets are then combined.

When the broodstock population contains 50 to 26 females, the eggs from each female are split into three equal sub-families. Each sub-family is fertilized by a different male. One cup of well water is added to each bucket and set aside for 30 seconds to one minute. All three sub-families are then combined.

When the broodstock population contains 25 females or less, the eggs from each female are divided into four equal sub-families. Each sub-family is fertilized by a separate male. The process is completed as previously mentioned to finish the spawning process. An effort is made to use all returning fish for spawning.

8.4 CRYOPRESERVED GAMETES

Milt is not cryopreserved as part of this program, and no cryopreserved gametes are used in this program.

8.5 INDICATE RISK AVERSION MEASURES THAT WILL BE APPLIED TO MINIMIZE THE LIKELIHOOD FOR ADVERSE GENETIC OR ECOLOGICAL EFFECTS TO LISTED NATURAL FISH RESULTING FROM THE MATING SCHEME

No natural-occurring fish are incorporated into the spawning operation.

SECTION 9. INCUBATION AND REARING

9.1.2 Cause for, and disposition of surplus egg takes

Surplus eggs may be generated (~ 10% above need) to provide a buffer against culling associated with the presence of bacterial kidney disease.

Page 49

9.1.3 Loading densities applied during incubation

Fertilized Chinook salmon eggs are loaded in Heath trays at densities that do not exceed 8,000 eggs per tray.

9.1.4 Incubation conditions

The maximum isolation incubation capacity of this facility is 6.272 million green eggs. The incubation room is supplied with two water sources to provide the desired temperature for incubation with a flow of 5 to 8 gpm per one-half stack.

Isolation incubation consists of 16 double stack Heath incubators with a total of 256 trays available for egg incubation. The maximum capacity of this facility is 2.048 million green eggs. The isolation incubation room is supplied with both water sources to provide the desired temperature for incubation with a flow of 5 to 8 gpm per stack.

Eyed-eggs are typically loaded in Heath tray baskets at densities not to exceed 8,000 eggs per basket.

Water flow to each incubator stack is checked periodically to insure that desired flows are maintained. Incubator water temperatures are tracked with recording thermographs and hand- held thermometers.

9.1.5 Ponding

Fry are typically ponded in hatchery vats when 80% of each incubation tray has completed yolk absorption. Temperature units are tracked throughout incubation to assist with the process of tracking incubation development. Spring Chinook salmon are typically ponded from December through the end of January. Flow and density indices are maintained to not exceed 1.3 and 0.3, respectively (Piper et al. 1982).

9.1.6 Fish health maintenance and monitoring

Following fertilization, eggs are typically water-hardened in a 100 ppm Iodophor solution for 30 minutes. During incubation, eggs routinely receive scheduled formalin treatments to control the growth of fungus. Treatments are typically administered three times per week at a concentration of 1667 ppm active ingredient. Formalin treatments are discontinued prior to hatching. Prior to hatching, dead eggs are picked on a regular schedule (approximately two times per week) to discourage the spread of fungus.

9.1.7 Indicate risk aversion measures that will be applied to minimize the likelihood for adverse genetic and ecological effects to listed fish during incubation

No adverse genetic or ecological effects to listed fish are anticipated as only hatchery-origin adults are spawned.

9.2 REARING

9.2.1 Provide survival rate data (average program performance) by hatchery life stage (fry to fingerling; fingerling to smolt) for the most recent twelve years or for years dependable data are available

Table 20. Brood year percent survival by life stage from 1997-2008. Brood Year Fry to fingerling Fingerling to smolt percent survival percent survival 1997 97.7 96.0 1998 99.7 99.9 1999 89.8 99.5 2000 99.3 99.3 2001 92.0 91.4 2002 99.2 99.4 2003 99.2 99.7 2004 99.4 99.2 2005 99.3 99.8 2006 97.8 92.8 2007 99.0 99.4 2008 99.9 N/A

9.2.2 Density and loading criteria (goals and actual levels)

At the swim-up stage of development, unfed fry are moved to inside vats and distributed as evenly as possible (typically 15,000 to 44,000 fish per vat at ponding). Density (DI) and flow (FI) indices are maintained to not exceed 0.30 and 1.3, respectively (Piper et al. 1982).

9.2.3 Fish rearing conditions

Clearwater Fish Hatchery - Chinook raceways are 200 feet x 10 feet x 3 feet deep. Eleven raceways have a total rearing space of 66,000 cubic feet. The raceways are supplied with water from both primary and secondary intakes and a mixing chamber, which allows water temperature to be controlled to rear Chinook. The designed rearing capacity of these raceways is 1.5 million smolts at a 0.3 DI. The estimated flow per raceway is 2.4 cfs.

Early rearing space consists of sixty concrete vats. Each measures 40 feet x 4 feet x 3 feet deep and contains 480 cubic feet of rearing space. This part of the facility can rear 5.9 million fish to a size of 287 fish/lb. at a 0.3 DI. The vats are supplied with water from each intake and have a flow of approximately 120 gallons per minute per vat when all vats are in use. An incubation jar is plumbed directly into each vat. The 60 incubator jars have a total capacity of 2.6 million eggs with a flow of 15 gpm per jar.

Page 51

Crooked River - The Crooked River facility has two raceways, measuring 145 feet x 20 feet x 4 feet deep, for a total of 23,200 cubic feet. These raceways have a capacity of 700,000 juvenile Chinook with a DI of 0.29. Water flow per raceway is 6 cfs. Each raceway is outfitted with three automated Nielson feeders. The adult trapping facility measures 10 feet x 12 feet x 4 feet deep with a total of 480 cubic feet. Water flow for the adult facility is 10 cfs. This facility has no provision for adult holding.

Powell - The rearing pond measures 165 feet x 65 feet x 5 feet deep and has 53,625 cubic feet of rearing space. The normal loading of 320,000 fish produces the best looking smolts and a DI significantly less than 0.3. The maximum design capacity is 500,000 fish with a DI of 0.092. Water flow through this pond is 6.24 cfs. A catwalk across the length of the pond supports eight automated Nielson feeders.

Red River - A 170-foot x 70-foot x 4-foot-6 inch deep rearing pond will rear a maximum of 320,000 Chinook smolts. The maximum design capacity is 500,000 fish with a DI of 0.092. Water flow through this pond is 6.24 cfs. This pond has a hypalon plastic liner with eight to ten inch diameter cobblestones on the inclined banks. The bottom of the pond is a bare liner, which aids in pond vacuuming. A catwalk runs the entire length of the rearing pond and holds eight automated Nielson feeders. Water flow through the pond is 4.09 cfs.

Hatchery and satellite water temperatures are monitored constantly with recording thermographs and checked routinely with hand held thermometers. Early rearing water temperatures (vat room) typically range from 4.4ºC to 13.3ºC. Dissolved oxygen and total dissolved gas are monitored monthly using hand held meters. Dissolved oxygen typically remains at 8.0 ppm or greater. Total dissolved gas typically averages 100%.

During early rearing, vats are cleaned daily and dead fish removed. During final rearing, outside raceways are cleaned every other day but dead fish are removed daily.

9.2.4 Indicate biweekly or monthly fish growth information (average program performance), including length, weight, and condition factor data collected during rearing, if available.

Juvenile spring Chinook salmon are sample-counted monthly. Fish length and weight are recorded. Condition factor and conversion rate are calculated. See Table 22 below.

9.2.5 Indicate monthly fish growth rate and energy reserve data (average program performance), if available.

Growth information (monthly length increase) for spring Chinook salmon reared at the Clearwater Fish Hatchery is presented below (Table 21). Data is IDFG unpublished information and represents the average monthly growth from 1994-2008.

9.2.6 Indicate food type used, daily application schedule, feeding rate range (e.g., % B.W./day and lbs/gpm inflow), and estimates of total food conversion efficiency during rearing (average program performance)

During early rearing, spring and summer Chinook salmon are fed a Bio-Oregon formula diet. Fish are fed every hour during this stage of development using automated feeders. Feeding rates range from 5.0% to 1.8% body weight per day. The average feed conversion rate during the early rearing period is 0.97 pounds of feed for every pound of weight gain.

During final rearing in outside raceways, spring Chinook salmon are fed BioOregon’s grower diet. Fish are fed every hour during this stage of development using pneumatic system. Feeding rates range from 2.0 to 1.8% body weight per day. The average feed conversion rate during this stage of development is 1.3 pounds of feed for every pound of weight gain.

9.2.7 Fish health monitoring, disease treatment, and sanitation procedures

At spawning, all spring Chinook salmon are screened for bacterial and viral pathogens. Eggs from females positive for bacterial kidney disease Renibacterium salmoninarum (BKD) are culled to an acceptable risk level established annually by all stakeholders.

Page 53

During rearing at Clearwater Fish Hatchery, regular fish health inspections are conducted. If disease agents are suspected or identified, more frequent inspections will be conducted. Recommendations for treating specific disease agents comes from the Idaho Department of Fish and Game Fish Health Laboratory in Eagle, ID.

Prior to release, the Eagle Fish Health Laboratory conducts a final pre-release fish health inspection.

9.2.8 Smolt development indices (e.g., gill ATPase activity), if applicable

No smolt development indices are developed in this program.

9.2.9 Indicate the use of "natural" rearing methods as applied in the program

No semi-natural or natural rearing objectives are applied during Chinook salmon incubation or rearing at the Clearwater Fish Hatchery. Acclimation ponds are used for some but not all juveniles released from this program.

9.2.10 Indicate risk aversion measures that will be applied to minimize the likelihood for adverse genetic and ecological effects to listed fish under propagation

ESA-listed, wild/natural spring Chinook salmon are not propagated at the Clearwater Fish Hatchery.

Page 56

10.5 FISH TRANSPORTATION PROCEDURES, IF APPLICABLE

All fish reared at the Clearwater Hatchery are transported off station for release in the upper basin of the Clearwater drainage. Fish are loaded into transport trucks using a Magic Valley Heliarc fish pump. The loading density guideline for transport vehicles is 0.5 pound of fish per gallon of water. The transport tanks are insulated to maintain good temperature control. Each tank is fitted with an oxygen system and fresh flow agitators. Maximum transport time is approximately 3-4 hours.

10.6 ACCLIMATION PROCEDURES (METHODS APPLIED AND LENGTH OF TIME)

Releases at Crooked River, lower Selway River and Clear Creek are acclimated for one hour in the truck prior to release. One half of the water in the truck tank is drained and replaced with water from the release site for acclimation. Releases at Powell and Red River are acclimated for four hours to ten days depending on weather conditions.

10.7 MARKS APPLIED, AND PROPORTIONS OF THE TOTAL HATCHERY POPULATION MARKED, TO IDENTIFY HATCHERY ADULTS

All general production harvest mitigation fish are marked with an adipose fin clip. Fish released as part of a supplementation effort have intact adipose fins but are coded-wire tagged. All Chinook salmon released from the Clearwater Fish Hatchery are marked or tagged to allow differentiation from natural-origin fish. The one exception to this are the parr released into the Upper Selway River which are marked with Oxytetracycline. See Table 22 for a list of mark types for each of the Clearwater Fish Hatchery Chinook salmon releases. The number of juveniles produced to meet supplementation objectives are specified in the 2008-2017 US v. Oregon Management Agreement. Annual in-season broodstock planning is adapted to actual adult returns for each brood year.

10.8 DISPOSITION PLANS FOR FISH IDENTIFIED AT THE TIME OF RELEASE AS SURPLUS TO PROGRAMMED OR APPROVED LEVELS

If juveniles are produced in excess of 10% of the programmed release, the IDFG will consult with the Nez Perce Tribe, USFW, and NMFS to develop an alternative location that poses low risk to natural anadromous and resident species, but still allows some contribution to the LSRCP program.

10.9 FISH HEALTH CERTIFICATION PROCEDURES APPLIED PRE- RELEASE

Between 45 and 30 days prior to release, a 20-fish pre-liberation sample is taken from each rearing lot to assess the prevalence of viral replicating agents and to detect the pathogens responsible for bacterial kidney disease and whirling disease. In addition, an organosomatic index is developed for each release lot. Diagnostic services are provided by the IDFG Eagle Fish Page 57

Health Laboratory.

10.10 EMERGENCY RELEASE PROCEDURES IN RESPONSE TO FLOODING OR WATER SYSTEM FAILURE

Emergency procedures are in place to guide activities in the event of a potential catastrophic event. Plans at the Clearwater Fish Hatchery include a trouble-shooting and repair process followed by the implementation of an emergency action plan if the problem cannot be resolved. Actions include fish consolidations and if necessary fish will be released directly to the Clearwater River.

Satellite facilities have similar plans in place. At these sites, it is generally easy to release fish directly to receiving waters if the emergency cannot be corrected.

10.11 INDICATE RISK AVERSION MEASURES THAT WILL BE APPLIED TO MINIMIZE THE LIKELIHOOD FOR ADVERSE GENETIC AND ECOLOGICAL EFFECTS TO LISTED FISH RESULTING FROM FISH RELEASES

Actions taken to minimize adverse effects on listed fish include:

Continuing fish health practices to minimize the incidence of infectious disease agents. Follow IHOT, AFS, and PNFHPC guidelines.

Marking hatchery-produced spring Chinook salmon for broodstock management. Smolts released for supplementation research will be marked differentially from other hatchery production fish.

Continuing to reduce effect of the release of large numbers of hatchery Chinook salmon at a single site by spreading the release over a number of days by trucking strategy or volitional release from ponds.

Attempting to program time of release to mimic natural fish for Clearwater River supplementation research releases, given the constraints of the hatchery and its transportation system.

Continuing to use broodstock for general production and supplementation research that exhibit life history characteristics similar to locally evolved stocks.

Continuing to segregate female spring Chinook salmon broodstock for BKD via ELISA. We will incubate each female's progeny separately and also segregate progeny for rearing. We will continue development of culling and rearing segregation guidelines and practices, relative to BKD.

Monitoring hatchery effluent to ensure compliance with National Pollutant Discharge Elimination System permit.

Continuing Hatchery Evaluation Studies (HES) to provide comprehensive monitoring and evaluation for LSRCP Chinook.

SECTION 11. MONITORING AND EVALUATION OF PERFORMANCE INDICATORS

11.1.1 Describe plans and methods proposed to collect data necessary to respond to each Performance Indicator identified for the program

In section 11.1.1 below, a series of tables, each followed by narrative, are provided for the purpose of adding detail with regards to plans and methods used to collect data necessary to respond to indicators listed in Section 1.10. Additionally, two columns are provided in the tables to indicate whether each indicator is:

1. Applicable to the hatchery program/s described in this HGMP (yes “Y” or no “N”) 2. Currently being monitored. a. For cells with a “Y”, the indicator is being monitored with funding provided by the hatchery mitigation program. b. For cells with a “C”, the indicator is being monitored, but is tied to a separately funded program (e.g. Idaho Supplementation Studies (ISS), Idaho Natural Production Monitoring Program (INPM), General Parr Monitoring (GPM) program etc.). Without continued funding for these programs, many of the M&E components will not occur. For example, the ISS program is scheduled to end in 2014 with some components ending in 2012. Funding to offset this loss needs to be identified to avoid significant M&E data gaps. c. For cells with a “Y/C”, the indicator is being monitored and is partially funded through the hatchery mitigation program. Other programs, such as those listed in 2b above, provide the remaining funding. d. For cells with an “N”, the indicator is not currently being monitored. For all indicators applicable to this HGMP that are not being addressed (N), a brief narrative is provided in Section 11.1.2 describing why the particular indicator is not being monitored.

Table 25, at the end of Section 11.1.1, provides a more detailed description of methodologies used in the basin that are more specific to VSP parameters.

1.1.1 – 1.1.2 The Nez Perce Tribe (NPT) and the Shoshone/Bannock Tribe (SBT) each authorize and manage fisheries. Both are non-selective fisheries that harvest both hatchery and natural returns. Each tribe conducts statistically based inseason fishery interview programs to estimate fishing effort, numbers of hatchery and natural origin Chinook salmon harvested and other species harvested, IDFG conducts similar statistically based harvest monitoring programs for non-Treaty recreational fisheries. For Chinook salmon fisheries IDFG and Tribal co-managers confer through scheduled inseason conferences to assess current ESA take and harvest shares. Steelhead fisheries are more protracted then Chinook salmon fisheries and require less inseason consultation. IDFG and Tribal co-managers share pre-season fisheries management plans and post- season estimates of harvest and ESA take.

1.1.3 – 1.2.1 Numbers of spring/summer Chinook salmon marked, tagged and total numbers released are in accordance with the production schedule in the 2008-2017 US vs.OR Management Agreement. Fisheries harvests in Idaho are not governed by terms of the US vs. OR agreement but Idaho and the respective Treaty Tribes manage in accordance with the principal of 50% Tribal and 50% non-tribal sharing of fish available for harvest in Idaho fisheries.

The mitigation objectives for the hatchery programs in Idaho are stipulated in the LSRCP and in the 1980 Hells Canyon Settlement Agreement. Each hatchery reports numbers of fish released by life stage in annual run or brood year reports. Representative sub-samples of fish released are code-wire tagged and PIT tagged to assess harvest contribution by release group and survival to the project area upstream of Lower Granite Dam. The majority of fish PIT tagged are representative of the run at large though the FCRPS. PIT tags detected among subsequent adult returns in the fish ladder at Lower Granite Dam are used to estimate in-season total facility specific returns to Lower Granite Dam. An independent estimate of the adult return over Lower Granite Dam is also complete post- season based on summed tribal and non-tribal harvest estimates and hatchery trapping data.

tagged. Steelhead intended to supplement natural populations are also released un- clipped. Few of these releases are coded-wire tagged. The marking rate by mark type for each release group of Chinook salmon and steelhead are inventories and reported annually.

Representative sub-samples of fish released from anadromous fish hatcheries in Idaho are code-wire tagged and PIT tagged to assess harvest contribution by release group. Coded- wire tag recovery data indicate that harvest of Snake River spring/summer Chinook salmon and steelhead are negligible in ocean fisheries. ODFW, WDFW, and CRITFC conduct statistically based fishery, interview biological sampling, and tag recovery programs in Tribal and non-Tribal fisheries in the mainstem and tributaries of the Columbia River in zones 1 through 6 and in the lower Snake River below Lower Granite Dam. Data from these sampling programs are used to estimate fishing effort, numbers of hatchery and natural origin fish harvested and released and in many cases contributions of specific mitigation hatchery releases to harvest. Results from these program are available in-season to assist harvest and hatchery managers and are reported in summary jointly by ODFW and WDFW.

IDFG, Nez Perce Tribe (NPT) and the Shoshone/Bannock Tribe (SBT) each authorize and manage fisheries in the boundary waters of the Snake River and in mainstems and tributaries of the Snake, Clearwater and Salmon Rivers. ODFW and WDFW also conduct recreational fisheries in the boundary waters of the Snake River shared by Idaho. Non- Tribal recreational fisheries are selective for adipose fin-clipped hatchery origin fish. Tribal fisheries are largely non-selective fisheries that harvest both hatchery and natural returns. IDFG, ODFW, WDFW and Tribes conducts statistically based in-season and post season fishery interview programs to estimate fishing effort, numbers of hatchery and natural origin fish harvested and released and other species encountered. Coded-wire tag recovery data from these programs are used to estimate hatchery specific contributions to age specific harvests by fishery.

IDFG and the Tribes estimate annual escapements of natural populations that are affected by fisheries targeting program fish through weirs operated in conjunction with hatchery programs. Statewide index counts of Chinook salmon redds are conducted to estimate numbers of spawners by population. IDFG and the Tribes have developed genetic stock identification standard and a sampling program at Lower Granite Dam to estimate escapement above the dam at the level of major spawning population groups for both Chinook salmon and steelhead.

Hatchery release numbers, mark rates among releases and sampling rates in Snake River and Columbia River mainstem and tributary fisheries downstream of Lower Granite Dam are reported by ODFW, WDFW, and CRITFC co-managers in the RMIS database maintained by the Pacific Sates Marine Fisheries Commission. IDFG, Nez Perce Tribe (NPT) and the Shoshone/Bannock Tribe (SBT) each authorize and manage fisheries in the boundary waters of the Snake River and mainstems and tributaries of the Snake, Clearwater and Salmon Rivers.

ODFW, WDFW and Tribes conducts statistically based in-season and post season fishery interview programs to estimate fishing effort, numbers of hatchery and natural origin fish harvested and released and other species encountered. Sampling rate by mark type, number of marks by program observed in fishery samples, and estimated total contribution of each population to by fishery are estimated and reported annually.

For hatchery Chinook salmon populations, IDFG completed annual run reconstructions based on population and age specific harvest estimates in Columbia River, Snake River and Snake River tributary fisheries and age specific rack returns. Run reconstruction data for each hatchery are used to develop hatchery specific pre-season run forecasts. Natural returns to Idaho are forecasted using similar run reconstructions of aggregate Snake River natural returns to Lower Granite Dam. IDFG and Tribal co-managers in the Snake Basin plan fisheries based on these forecasts. IDFG and Tribal co-managers confer through scheduled in-season conferences to assess accuracy of the preseason forecast based on in- season estimates of the actual hatchery returns from real-time PIT tag detections in the Columbia River hydro-system. Co-managers also assess inseason estimates of ESA take, harvest shares, and the disposition of hatchery returns to racks in excess of broodstock needs.

Steelhead fisheries are more protracted then Chinook salmon fisheries and require less in- season consultation. IDFG and Tribal co-managers share pre-season fisheries management plans and post-season estimates of harvest and ESA take.

IDFG, Nez Perce Tribe (NPT) and the Shoshone/Bannock Tribe (SBT) each authorize and manage fisheries in the boundary waters of the Snake River and mainstems and tributaries of the Snake, Clearwater and Salmon Rivers. ODFW and WDFW also conduct recreational fisheries in the boundary waters of the Snake River shared by Idaho. Non-Tribal recreational fisheries are selective for adipose fin-clipped hatchery origin fish. Tribal fisheries are largely non-selective fisheries that harvest both hatchery and natural returns.

Sampling rate by mark type, number of marks by program observed in fishery samples, and estimated total contribution of each population to by fishery are estimated and reported annually

Numbers of spawners by age are estimated annually by weir counts, spawning ground surveys or a combination of both methods for all Chinook salmon conservation programs. All fish passed upstream of weirs are identified by marks or tags as hatchery or natural origin and are sampled for age, sex, and size. Index redd counts are conducted on all natural spawning areas affected by supplementation programs and representative portions of carcasses on spawning grounds are sampled for marks, or tags and for age, sex, and size information. Annual estimated of spawners by age are used to monitor inter-annual spawner-recruit trends.

Because steelhead migration into spawning areas in Idaho coincides with high flows it is not possible to accurately estimate total spawning escapement in supplemented streams using weir counts or spawning ground surveys. Partial escapement estimated from weirs on the upper reaches of spawning areas are available for each supplemented system but escapements to lower reaches cannot be measured. Additional funding will be required to build permanent weirs below spawning areas on supplemented systems. Additional funding is also required to implement parental based tagging programs to distinguish progeny from hatchery origin from natural origin spawners in these systems.

Releases of fish from supplementation programs are marked or tagged to differentiate them from fish released for harvest mitigation and from natural origin fish. Mark rate by mark type for all releases are inventoried and reported. Screw traps are used to estimate numbers natural origin out-migrants from the supplemented population. All fish passed upstream of weirs are identified by marks or tags as hatchery or natural origin and are sampled for age, sex, and size. Index redd counts are conducted on all natural spawning areas affected by supplementation programs and representative portions of carcasses on spawning grounds are sampled for marks, or tags and for age, sex, and size information. Annual estimated of spawners by age are used to monitor inter-annual spawner-recruit trends.

While the above methods allow us to estimate numbers of natural origin and hatchery origin spawners on the spawning grounds, they do not allow us to estimate the relative contribution of hatchery and natural spawners to natural production. IDFG, Tribal and federal co-managers in the Snake basin are currently collecting genetic samples from all Page 67

fish spawned in anadromous hatcheries and all natural and hatchery fish passed above weirs associated with hatchery programs. IDFG has worked in conjunction with CRITFC to build a library of genetic markers that can be used to identify individual parents of juveniles produced by adults sampled in hatchery broodstocks or from adults passed above weirs to spawn. Parental based analysis of juvenile production can be used to assess the relative contributions of individual spawning crosses (i.e. hatchery x hatchery, hatchery x natural, or natural x natural). While we currently have the samples in hand to do this analysis and will continue to collect those samples, we have no funding to process the samples for parental analysis.

Hatcheries or hatchery satellite facilities where broodstocks are collected are typically located on the tributary where the parent natural population for the hatchery broodstock resides. Hatchery and natural returns at those locations are trapped and enumerated at weirs run throughout the adult migration. Long time series of historic daily migration data are available at all facilities for both hatchery and natural returns. Managers use historic data to construct timing curves of average daily proportion of the run by date. These timing curves are used to project the numbers of natural fish returning to the weir and the numbers of the proportion of the annual broodstock need that should be collected by day. All hatchery and natural fish captured at the weirs are sampled for age, sex, and size data. Age is typically determined by length frequency analysis using age length relationships from known age coded-wire tagged fish.

All natural fish intercepted at hatchery facilities where broodstocks are maintained as a segregated population, all natural fish trapped during broodstock collection are released to spawn naturally in the available habitat upstream of the weir. At hatchery programs where integrated broodstock are maintained or are being developed, the natural and hatchery composition of the broodstock and the affected natural populations are carefully monitored and controlled based sliding scales specific to each program. The proportions of natural fish into the hatchery broodstock and hatchery fish into the natural spawning population are based on a sliding scale of natural abundance. Success of the program is predicated on an average measure of percent natural influence in the hatchery and natural populations across generations.

The overwhelming majority of hatchery produced spring/summer Chinook salmon and all steelhead in Idaho are released as smolts. Representative portions of all smolt releases are PIT tagged and migratory timing of these fish is known. Hatchery smolts quickly exit terminal tributary rearing areas. While mainstem migration among hatchery smolts corresponds with typical timing observed among natural origin fish no significant competitive interactions during their brief seaward migratory period have been documented.

Where parr and presmolt release programs and egg box programs are implemented in some areas where natural production is severely depressed. The size of these programs are small and metered by best available estimates of the abundance of natural fish and habitat capacity.

At all broodstock collection sites for spring/summer Chinook salmon hatcheries and steelhead hatcheries operated by Idaho Department of Fish and Game, daily records of Page 68

adult fish trapped and their disposition (i.e. held for brood, passed above weir to spawn, etc.) are maintained. Representative fractions of all natural origin and hatchery fish trapped are sampled for age, sex and size. Daily spawning records, incubator loading densities, survival at various stages of development, and fry emergence timing are documented for each hatchery. Juvenile growth and survival are monitored by life stage and all production fish are adipose fin-clipped and or coded-wire tagged. A representative sample of all smolt release groups are PIT tagged. All data relative to hatchery adult collection, spawning, incubation, and rearing data are stored in a standardized relational data base that is maintained collaboratively with Tribal, Federal and state co-managers in the Snake River Basin. All coded wire and PIT tagging and release data are entered into RMIS and PITAGIS databases maintained by the Pacific States Marine Fisheries Commission. PIT tag detections at key points in the seaward migration of juvenile releases from hatcheries are used to estimate migration timing and survival.

The Idaho Supplementation Studies is a large scale effectiveness monitoring program that is designed to track production and productivity in supplemented (treated) verses un- supplemented (control) streams. It is a long term program that is designed to last approximately 20 years and assess production and productivity prior to, during and after treatment in approximately 15 streams. The study is conducted collaboratively by IDFG, the Nez Perce Tribe, the Shoshone/ Bannock Tribes, and the USFWS. The study collects comparative production and productivity measures in approximately 15 control streams that have been paired with treatment sites and monitored across the duration of the study. Tributaries where Sawtooth, Pahsimeroi, McCall, Clearwater, and Kooskia hatcheries release spring/summer Chinook salmon are among the study sites. At each site, juvenile screw traps assess hatchery and natural juvenile outmigration timing, abundance, age structure, condition and survival. Representative portions of the natural outmigration are PIT tagged to assess timing and survival to Lower Granite Dam. ISS also monitors adult return in treatment streams at weirs and in treatment and control streams by systematic red counts in natural spawning areas through spawning. Weir and redd count data provide data on adult spawn timing, age structure, genetic composition, and spatial distribution.

The Idaho Natural Production Monitoring Program and the Idaho Steelhead Monitoring and Evaluation Study monitor adult and juvenile segments of natural Chinook salmon and steelhead populations other than those included for effectiveness monitoring in the ISS project. Snorkel surveys have historically been conducted in representative standardized index sections of streams where natural populations of Chinook and steelhead spawn and rear. Snorkel surveys provide estimates of relative annual abundance, temporal, and spatial distribution of juvenile salmon and steelhead. Systematic sampling of juveniles for age and tissues for genetic analyses provide estimates of age composition and genetic structure and diversity in each population.

The Idaho Natural Production Monitoring program also oversees the systematic redd count survey program for natural populations of Chinook salmon throughout Idaho. Data from this program are available from the 1950’s through the present and provide data to estimate historic abundance and distribution of spawners in all extant natural populations of Chinook salmon in Idaho. During systematic spawning ground surveys, carcasses of adult spawners are also sampled for scales, sex and size information and for tissues analyzed to characterize the genetic structure of the populations.

Applied by: The population estimate Fish per Redd at a weir site, minus broodstock and mortalities and harvest, divided by the total number of redds located upstream of the weir. Number of female spawners divided by the total number of redds above weir. Applied in 2 ways: 1) The population estimate at a weir site multiplied by the weir derived proportion of females, minus the number of female pre-spawn mortalities, divided by the total number Female Spawner per Redd of redds located upstream of the weir, and 2) DIDSON application calculated as in 1 above but with proportion females from carcass recoveries.

Gauss software is (Aptech Systems, Maple Valley, Washington) is used to estimate Juvenile Emigrant emigration estimates. Estimates are given for parr pre-smolts, smolts and the entire Abundance migration year. Calculations are completed using the Bailey Method and bootstrapping for 95% CIs. Gauss program developed by the University of Idaho (Steinhorst 2000). Smolt estimates, which result from juvenile emigrant trapping and PIT tagging, are derived by estimating the proportion of the total juvenile abundance estimate at the tributary comprised of each juvenile life stage (parr, presmolt, smolt) that survive to first mainstem dam. It is calculated by multiplying the life stage specific abundance estimate (with standard error) by the life stage specific survival estimate to first mainstem dam (with Smolts standard error). The standard error around the smolt equivalent estimate is calculated using the following formula; where X = life stage specific juvenile abundance estimate and Y = life stage specific juvenile survival estimate: Var( XY) 22 E()()()()()() X Var Y E Y Var X Var X Var Y This will not be in the raw or summarized performance database.

The number of adult returns from a given brood year returning to a point (stream mouth, weir) divided by the number of smolts that left this point 1-5 years prior. Calculated for wild and hatchery origin conventional and captive brood fish separately. Adult data applied in two ways: 1) SAR estimate to stream using population estimate to stream, 2) adult PIT tag SAR estimate to escapement monitoring site (weirs, LGR), and 3) SAR estimate with harvest. Accounts for all harvest below stream.

Smolt-to-adult return rates are generated for four performance periods; tributary to tributary, tributary to tributary, tributary to first mainstem dam, first mainstem dam to first mainstem dam, and first mainstem dam to tributary.

First mainstem dam to first mainstem dam SAR estimates are calculated by dividing the number of PIT tagged adults returning to first mainstem dam by the estimated number of PIT tagged juveniles at first mainstem dam. Variances around the point estimates are calculated as described above.

Tributary to tributary SAR estimates for natural and hatchery origin fish are calculated using PIT tag technology as well as direct counts of fish returning to the drainage. PIT tag SAR estimates are calculated by dividing the number of PIT tag adults returning to the tributary (by life stage and origin type) by the number of PIT tagged juvenile fish migrating from the tributary (by life stage and origin type). Overall PIT tag SAR estimates for natural fish are then calculated by averaging the individual life stage specific SAR’s. Direct counts are calculated by dividing the estimated number of natural and hatchery-origin adults returning to the tributary (by length break-out for natural fish) by the estimated number of Smolt-to-Adult Return Rate natural-origin fish and the known number of hatchery-origin fish leaving the tributary.

Tributary to first mainstem dam SAR estimates are calculated by dividing the number of PIT tagged adults returning to first mainstem dam by the number of PIT tagged juveniles tagged in the tributary. There is no associated variance around this estimate. The adult detection probabilities at first mainstem dam are near 100 percent.

First mainstem dam to tributary SAR estimates are calculated by dividing the number of PIT tagged adults returning to the tributary by the estimated number of PIT tagged juveniles at first mainstem dam. The estimated number of PIT tagged juveniles at first mainstem dam is calculated by multiplying lifestage specific survival estimates (with standard errors) by the number of juveniles PIT tagged in the tributary. The variance for the estimated number of PIT tagged juveniles at first mainstem dam is calculated as follows, where X = the number of PIT tagged fish in the tributary and Y = the variance of the lifestage specific survival estimate: 2 Var( XY) X Var() Y The variance around the SAR estimate is calculated as follows, where X = the number of adult PIT tagged fish returning to the tributary and Y = the estimated number of juvenile PIT tagged fish at first mainstem dam : X EX2 Var() Y Var Y EY() EY 2

Adult to adult calculated for naturally spawning fish and hatchery fish separately as the Progeny-per- Parent Ratio brood year ratio of return adult to parent spawner abundance using data above weir.

Derive adult escapement above juvenile trap multiplied by the pre-spawning mortality estimate. Adjusted for redds above juv. Trap. Recruit per spawner estimates, or juvenile abundance (can be various life stages or Recruit/spawner locations) per redd/female, is used to index population productivity, since it represents the (R/S)(Smolt Equivalents quantity of juvenile fish resulting from an average redd (total smolts divided by total redds) per Redd or female) or female. Several forms of juvenile life stages are applicable. We utilize two measures: 1) juvenile abundance (parr, presmolt, smolt, total abundance) at the tributary mouth, and 2) smolt abundance at first mainstem dam. Percent of female adults that die after reaching the spawning grounds but before spawning. Pre-spawn Mortality Calculated as the proportion of “25% spawned” females among the total number of female carcasses sampled. (“25% spawned” = a female that contains 75% of her egg compliment].

Survival by life stage to and through the hydrosystem Mainstem Dams is possible if enough PIT tags are available from the stream. Using tags from all life stages combined we will calculate (SURPH) the survival to all mainstem dams. Post-release survival of natural and hatchery-origin fish are calculated as described above Post-release Survival in the performance measure “Survival to first mainstem dam and Mainstem Dams”.

Calculated for wild and hatchery origin conventional and captive brood adult returns. Accessed via scale method, dorsal fin ray ageing, or mark recoveries. Juvenile Age is determined by brood year (year when eggs are placed in the gravel) Then Age is determined by life stage of that year. Methods to age Chinook captured in screwtrap are by dates; fry – prior to July 1; parr – July 1-August 31; presmolt – September 1 – Age Structure December 31; smolt – January 1 – June 30; yearlings – July 1 – with no migration until following spring. The age class structure of juveniles is determined using length frequency breakouts for natural-origin fish. Scales have been collected from natural-origin juveniles, however, analysis of the scales have never been completed. The age of hatchery-origin fish is determined through a VIE marking program which identifies fish by brood year. For steelhead we attempt to use length frequency but typically age of juvenile steelhead is not calculated. Age distribution of spawners on spawning ground. Calculated for wild and hatchery Age–at–Return conventional and captive brood adult returns. Accessed via scale method, dorsal fin ray ageing, or mark recoveries. Juvenile Age is determined by brood year (year when eggs are placed in the gravel) Then Age is determined by life stage of that year. Methods to age Chinook captured in screwtrap are by dates; fry – prior to July 1; parr – July 1-August 31; presmolt – September 1 – December 31; smolt – January 1 – June 30; yearlings – July 1 – with no migration until following spring. The age class structure of juveniles is determined using length frequency Age–at-Emigration breakouts for natural-origin fish. Scales have been collected from natural-origin juveniles, however, analysis of the scales have never been completed. The age of hatchery-origin fish is determined through a VIE marking program which identifies fish by brood year. For steelhead we attempt to use length frequency but typically age of juvenile steelhead is not calculated. Size distribution of spawners using fork length and mid-eye hypural length. Raw database Size-at-Return measure only. Fork length (mm) and weight (g) are representatively collected weekly from natural juveniles captured in emigration traps. Mean fork length and variance for all samples within a lifestage-specific emigration period are generated (mean length by week then Size-at-Emigration averaged by lifestage). For entire juvenile abundance leaving a weighted mean (by lifestage) is calculated. Size-at-emigration for hatchery production is generated from pre release sampling of juveniles at the hatchery.

Condition factor by life stage of juveniles is generated using the formula: K = (w/l3)(104) Condition of Juveniles at where K is the condition factor, w is the weight in grams (g), and l is the length in Emigration millimeters (Everhart and Youngs 1992). Life History Life

Juvenile emigration timing is characterized by individual life stages at the rotary screw trap Juvenile Emigration and Lower Granite Dam. Emigration timing at the rotary screw trap is expressed as the Timing percent of total abundance over time while the median, 0%, 10, 50%, 90% and 100% detection dates are calculated for fish at first mainstem dam. Unique detections of juvenile PIT-tagged fish at first mainstem dam are used to estimate migration timing for natural and hatchery origin tag groups by lifestage. The actual Median, 0, 10%, 50%, 90% and 100% detection dates are reported for each tag group. Mainstem Arrival Timing Weighted detection dates are also calculated by multiplying unique PIT tag detection by a (Lower Granite) life stage specific correction factor (number fish PIT tagged by lifestage divided by tributary abundance estimate by lifestage). Daily products are added and rounded to the nearest integer to determine weighted median, 0%, 50%, 90% and 100% detection dates. Physical Habitat TBD

Method dependent upon marking program (census obtained when 100% are marked). In-hatchery survival is calculated during early life history stages of hatchery-origin juvenile Chinook. Enumeration of individual female's live and dead eggs occurs when the eggs are picked. These numbers create the inventory with subsequent mortality subtracted.

11.1.2 Indicate whether funding, staffing, and other support logistics are available or committed to allow implementation of the monitoring and evaluation program

Section 11.1.1 describes the methods and plans to address the standards and indicators listed in Section 1.10. The table includes a field indicating whether or not the indicator is being monitored.

For cells with a “Y”, the indicator is being monitored with funding provided by the hatchery mitigation program.

For cells with a “C”, the indicator is being monitored, but is tied to a separately funded program (e.g. Idaho Supplementation Studies (ISS), Idaho Natural Production Monitoring Program (INPM), General Parr Monitoring (GPM) program etc.). Without continued funding for these programs, many of the M&E components will not occur. For example, The ISS program is scheduled to end in 2014 with some components ending in 2012. Funding to offset this loss needs to be identified to avoid significant M&E data gaps.

For cells with a “Y/C”, the indicator is being monitored and is partially funded through the hatchery mitigation program. Other programs, such as those listed in 2b above, provide the remaining funding.

For cells with an “N”, the indicator is not currently being monitored. For all applicable indicators that are not being addressed (N), a brief narrative is provided below describing why that particular indicator is not being monitored.

Standard or Indicator - Standards are in bold font, Indictors are in italic font and underlined

3.2 The current status and trends of natural origin populations likely to be impacted by hatchery production are monitored.- With the existing infrastructure, we can monitor abundance and productivity of the natural population in the uppermost reaches of the SF Clearwater River (in Red River and Crooked River). Assessing these parameters in the lower S.F. Clearwater will require new infrastructure.

Page 77

3.4 Effects of strays from hatchery programs on non-target (unsupplemented and same species) populations remain within acceptable limits.- Representative fish from all release groups are tagged with CWT and PITs. If fish from these releases are recovered as strays, PITs and CW will identify their cohort and origin. Additionally, since 2008 all broodstock used to generate releases have been tissue sampled as part of a Parental Based Tagging (PBT) program. This will allow any fish released from any of the hatcheries in Idaho to be assigned to their hatchery of origin and to a specific cohort. To date, only tissue samples have been collected. Funding to genotype and maintain that genetic database is still lacking.

3.5 Habitat is not a limiting factor for the affected supplemented population at the targeted level of supplementation.- While specific habitat capacity is not monitored, managers do not feel that the number of juveniles released for supplementation will exceed habitat carrying capacity.

3.6 Supplementation of natural population with hatchery origin production does not negatively impact the viability of the target population.- Chinook salmon populations in the Clearwater River were extirpated and subsequently reestablished primarily with Rapid River hatchery stock. We do not have the pre-hatchery influenced period data on abundance and productivity in the Clearwater River to compare to a post treatment supplementation management. Adult abundance is monitored at Red River, Crooked River, American River, Lolo Creek and several tributaries in the Lochsa and Selway Rivers. Juvenile production monitoring (screw traps and snorkeling) does occur annually through the ISS and INPM programs.

3.7.2 Natural spawning success of hatchery-origin fish must be similar to that of natural-origin fish.- Genetic samples are collected from all Chinook salmon passed above the weirs on Red, Crooked River, and Lolo Creek (check with NPT), and Crooked Fork Creek. This will allow the ability to assign progeny to the parents released above the weirs. There is currently no funding available to process and analyze these samples. We are unable to monitor reproductive success of fish spawning below the weirs on Red and Crooked rivers

3.10.1 Detectable changes in rate of occurrence and spatial distribution of disease, parasite or pathogen among the affected hatchery and natural populations - IDFG maintains a formalized fish health monitoring program for stocks propagated and reared at the hatchery facilities. IDFG has not prioritized the need to develop a formalized monitoring program for natural populations adjacent to the hatchery program. However, if mortalities occur or are observed during routine field operations and data collection events, samples are collected and delivered to the IDFG Fish Health Lab for analysis. Additionally, fish health samples collected by the USFWS as part of the National Wild Fish Heath Survey Database (www.esg..edu/nfhdb/) are collected throughout Idaho.

For hatchery-origin releases, between 45 and 30 d prior to release, a 60 fish pre-liberation sample is taken from each rearing lot to assess the prevalence of viral replicating agents and to detect the pathogens responsible for bacterial kidney disease and whirling disease. In addition, an organosomatic index is developed for each release lot. Diagnostic services are provided by the IDFG Fish Health Laboratory.

11.2) Indicate risk aversion measures that will be applied to minimize the likelihood for adverse genetic and ecological effects to listed fish resulting from monitoring and evaluation activities.

Risk aversion measures for monitoring and evaluation activities associated with the evaluation of the Lower Snake River Compensation Program are specified in our ESA Section 7 Consultation and Section 10 Permit 1124. A brief summary of the kinds of actions taken is provided.

Adult handling activities are conducted to minimize impacts to ESA-listed, non-target species. Adult and juvenile weirs and screw traps are engineered properly and installed in locations that minimize adverse impacts to both target and non-target species. All trapping facilities are constantly monitored to minimize a variety of risks (e.g., high water periods, high emigration or escapement periods, security).

Adult spawner and redd surveys are conducted to minimize potential risks to all life stages of ESA-listed species. The IDFG conducts formal redd count training annually. During surveys, care is taken to not disturb ESA-listed species and to not walk in the vicinity of completed redds.

Snorkel surveys conducted primarily to assess juvenile abundance and density are conducted in index sections only to minimize disturbance to ESA-listed species. Displacement of fish is kept to a minimum.

Marking and tagging activities are designed to protect ESA-listed species and allow mitigation harvest objectives to be pursued/met. Hatchery produced fish are visibly marked to differentiate them from their wild/natural counterpart.

SECTION 12. RESEARCH

12.1 OBJECTIVE OR PURPOSE

Indicate why the research is needed, its benefit or effect on listed natural fish populations, and broad significance of the proposed project

Hatchery Supplementation Research The Idaho Salmon Supplementation (ISS) research study was initiated to evaluate the benefits and risks of using a supplementation strategy to increase natural production. It is the only large scale study of its kind in the Columbia Basin. The ISS project has utilized existing hatchery facilities that are funded by the LSRCP program and used LSRCP Page 79

program fish to create supplementation broodstocks. For obvious reasons, the LSRCP and ISS programs are tightly linked with respect to monitoring and evaluating both hatchery- and natural-origin Chinook salmon associated with and adjacent to the hatchery program. This research program is scheduled to be completed in 2014.

The following excerpts were taken from the 1997-2001 ISS progress report (Lutch et al. 2003):

The Idaho Supplementation Studies (ISS) project is a collaborative study between Idaho Department of Fish and Game (IDFG), the Nez Perce Tribe, the Shoshone Bannock Tribe, and the U.S. Fish and Wildlife Service. It was developed to determine the benefits and risks associated with hatchery supplementation of Chinook salmon Oncorhynchus tshawytscha in the Snake River basin. Because the scope of study is broad, streams included were distributed among the cooperating agencies, which operate under an umbrella agreement to maintain consistency for all research activities.

The ISS study design was implemented in 1992 (Bowles and Leitzinger 1991) with the following goals in mind: 1) evaluate the efficacy of using hatchery fish to restore or augment production in natural populations of spring and summer Chinook salmon in the Salmon and Clearwater River subbasins of Idaho, 2) evaluate the long-term impacts of supplementation with hatchery origin Chinook salmon on the survival and fitness of natural populations, and 3) evaluate hatchery releases at different life stages with respect to these same measures of production and productivity. To achieve these goals, a long-term experiment was designed to compare production and productivity measures between a group of experimentally supplemented (treatment) streams and a group of untreated (control) streams where natural production has experienced little or no hatchery influence. The following objectives were established to accomplish the goals of the ISS study:

1. Monitor and evaluate the effects of supplementation on the abundance of naturally produced juveniles and resultant adult returns,

2. Monitor and evaluate changes in natural productivity and genetic composition of target and adjacent populations following supplementation,

3. Determine which supplementation strategies (e.g., smolt versus parr release) provide the highest response in natural production without adverse affects on productivity, and

4. Develop supplementation recommendations.

Research tasks are distributed among three project phases. During Phase I, broodstock for the first generation (F1) of supplementation treatments was developed from crosses of locally derived hatchery and wild/natural origin Chinook salmon. These F1 fish were incubated in the hatchery and reared to parr, presmolt, or smolt life stages. They were uniquely marked prior to release in natural rearing areas to make them distinguishable from other hatchery origin and

Page 80

naturally produced Chinook salmon. During Phase II of the study, adult returns from F1 supplementation releases were crossed with adult returns from naturally produced juveniles. Natural origin adults comprise a minimum of 50% of the fish used in the crosses to produce the second generation (F2) of supplementation fish. All remaining natural origin and supplementation recruits are allowed to spawn naturally, as long as supplementation adults do not numerically exceed the number of natural fish. In Phase III, supplementation with juvenile outplants ceases, but adult returns from supplementation juveniles are allowed to enter natural spawning areas and spawn with each other or fish of natural origin to naturally supplement the F3 generation. Monitoring and evaluation of juvenile production and resulting adult returns are conducted on the F1, F2, and F3 generations to provide a means to evaluate the effects of supplementation on natural production and productivity.

Continuous coordination between the LSRCP hatchery evaluation study, Idaho Department of Fish and Game’s BPA-funded ISS research is required because these programs overlap in several areas including: juvenile outplanting, broodstock collection, spawning (mating) strategies, and natural production and productivity monitoring.

15.2 DESCRIPTION OF NON-ANADROMOUS AQUATIC SPECIES AND HABITAT THAT MAY BE AFFECTED BY HATCHERY PROGRAM

This program releases juvenile hatchery spring Chinook into the Clearwater River subbasin and bull trout (threatened) are the only non-anadromous aquatic ESA-listed species in the subbasin. Bull trout life history, status and habitat use in Clearwater River subbasin is summarized below.

General Species Description, Status, and Habitat Requirements

Bull trout (members of the family Salmonidae) are a species of char native to Nevada, Oregon, Idaho, Washington, Montana and western Canada. While bull trout occur widely across the western United States, they are patchily distributed at multiple spatial scales from river basin to local watershed, and individual stream reach levels. Due to widespread declines in abundance, bull trout were initially listed as threatened in Idaho in 1998, and listed throughout their coterminous range in the United States in 1999. On January 13, 2010, the USFWS proposed to revise its 2005 designation of critical habitat for bull trout, which includes a substantial portion of the Clearwater River subbasin (1,679 stream miles were proposed as critical habitat in the Clearwater River subbasin).

Page 87

Throughout their range, bull trout have declined due to habitat degradation and fragmentation, blockage of migratory corridors, poor water quality, past fisheries management (such as over harvest and bounties), and the introduction of non-native species such as brown, lake and brook trout. Range-wide, several local extinctions have been documented. Many of the remaining populations are small and isolated from each other, making them more susceptible to local extinctions. However, recent work in Idaho concluded that despite declines from historical levels, Idaho bull trout are presently widely distributed, relatively abundant, and apparently stable (High et al. 2008). High et al. (2008) further concluded that the Clearwater River bull trout Recovery Unit exhibited an overall increasing trend, with three of four available post-1994 abundance trends significantly positive in this subbasin, although the subbasin had the lowest mean linear bull trout density of all recovery units sampled across Idaho (1.2 bull trout/100 m in the Clearwater River recovery unit compared to the high of 22.1 bull trout/100 m in the Clark Fork River recovery unit).

Bull trout exhibit a wide variety of life history types, primarily based on general seasonal migration patterns of subadult and adult bull trout between headwater spawning and rearing streams to other habitats (usually downstream) for foraging and overwintering, including resident (residing in small headwater streams for their entire lives); fluvial (migrating to larger river systems); adfluvial (migrating to lakes or reservoirs); and anadromous (migrating to estuarine or marine waters) (Goetz et al. 2004). All of these life history strategies are present in the Clearwater River subbasin, except anadromy. Fluvial and resident bull trout populations have been commonly observed throughout the current range of bull trout in the Clearwater River subbasin (USFWS 2002). There are two naturally adfluvial bull trout populations within the Clearwater River Recovery Unit. One is associated with Fish Lake in the upper North Fork Clearwater River drainage and the other is associated with Fish Lake in the Lochsa River drainage (USFWS 2002), both of which are outside the influence of this spring Chinook hatchery program.

Bull trout spawning and rearing requires cold water temperatures; generally below 16°C during summer rearing, and less than about 10°C during spawning (Dunham et al. 2003). Juvenile bull trout require complex rearing habitats (Dambacher and Jones 1997, Al-Chokhachy et al. 2010). Migratory adult and subadult bull trout are highly piscivorous (Lowery et al. 2009). Additionally, migratory adults need unobstructed connectivity to diverse habitats where forage fish species are plentiful and where water temperatures are relatively cool (less than about 18°C maximum during migration) (Howell et al. 2009).

Population Status and Distribution by Core Area

Bull trout are distributed throughout most of the large rivers and associated tributary systems of the Clearwater River subbasin. The Clearwater River Recovery Unit consists of 7 core areas, with a total of 45 local populations distributed among them as defined in the bull trout Draft Recovery Plan (USFWS 2002). The recovery team also identified 27 potential local populations. The Clearwater spring Chinook program releases hatchery juveniles into four bull trout core areas, including the South Fork Clearwater, Lower and Middle Fork Clearwater, Lochsa, and Selway rivers. The following information on these four bull trout core areas and local population status and habitat use within them, is summarized from the bull trout Draft Recovery Plan (USFWS 2002) unless otherwise cited.

Page 88

South Fork Clearwater River Core Area The South Fork Clearwater River Core Area has the most comprehensive data for bull trout within the Clearwater River Recovery Unit obtained through a multi-year study by IDFG that documented juvenile distribution in most tributaries and headwater streams. Bull trout are currently known to use spawning and rearing habitat in five stream complexes within the South Fork Clearwater, which are defined as local populations in the Draft Recovery Plan. These local populations include Red River (including Upper and West Fork of South Fork Red River), Crooked River, Newsome Creek, Tenmile Creek, and Johns Creek. Potential local populations include American River, Meadow Creek, and Mill Creek. The current abundance and distribution of bull trout in the core area is considered lower than historic levels, with low incidence of fluvial migratory adults, indicating the predominance of a resident life history. Significant fluvial bull trout migration occurs in the Crooked River watershed.

The bull trout 5-year status review conducted in 2006 (USFWS 2008) determined the South Fork Clearwater River Core Area had adult abundance levels in the 1,000-2,500 fish range, occupation of stream miles in the 125-650-mile range, an unknown short-term trend, substantial/imminent threat to persistence, and a final ranking of “at risk” to become extirpated (Table 26). More recent analysis by High et al. (2008) determined that a negative rate of population change occurred pre-1994, but post-1994 was significantly positive overall, indicating an increasing population trend post-1994 (19-year record at 85 survey sites) (see Table 26).

Estimates that were unavailable due to inadequate data are indicated (NA). Page 89

Lochsa River Core Area Bull trout are currently known to use spawning and rearing habitat in 16 streams or stream complexes within the Lochsa River drainage. These local populations include Fishing (Squaw), Legendary Bear (Papoose), Boulder, Fox, Shotgun, Crooked Fork/Hopeful, Rock, Haskell, Colt Killed (White Sands), Beaver, Storm, Brushy Fork, Spruce, Twin, Walton, and Lower Warm Springs creeks. Potential local populations include Post Office, Weir, Indian Grave, Lake, Fish, Hungary, Boulder, Old Man, Split, Fire, Coolwater, Canyon, Deadman, and Pete King creeks. Fluvial bull trout are thought to use the majority of spawning and rearing habitat except for Spruce and Shotgun creeks, which are likely resident populations due to migration barriers. Subadult and adult bull trout are suspected to use nearly all accessible areas of the core area for foraging and migration.

The bull trout 5-year status review conducted in 2006 (USFWS 2008) determined the Lochsa River Core Area had adult abundance levels in the 50-250 range, occupation of stream miles in the 125-650 range, a stable short-term trend, moderate/imminent threat to persistence, and a final ranking of “at risk” to become extirpated (Table 26). More recent analysis by High et al. (2008) determined that a negative rate of population change occurred pre-1994, but post-1994 was significantly positive overall, indicating an increasing population trend post-1994 (19-year record at 43 survey sites) (Table 27). Furthermore, the rate of increase in the Lochsa River Core Area post-1994 was the highest of 4 core areas analyzed in the Clearwater River Recovery Unit, and the second highest of 17 core areas analyzed in Idaho.

Selway River Core Area The Selway River supports significant fluvial bull trout populations that are widely distributed through the core area in variable densities, as well as widely distributed resident local populations in some upper tributary reaches. Local populations are well-connected within this core area. Bull trout are currently known to use spawning and rearing habitat in at least 10 streams or stream complexes within the Selway River drainage. These local populations include Meadow, Moose, Running, White Cap, Bear, Deep, Indian, and Magruder creaks, and the Upper Selway and Little Clearwater rivers. Potential local populations include Marten, Mink, Gedney, Three Links, and O’Hara creeks. Intensive distribution surveys have not been conducted throughout the core area, and additional undocumented spawning and rearing areas likely exist. Total abundance is unknown, but stream survey data collected in 1997 suggest that fish density is relatively high.

The bull trout 5-year status review conducted in 2006 (USFWS 2008) determined the Selway River Core Area had an unknown adult abundance level, occupation of stream miles in the 125- 650 range, an unknown short-term trend, widespread/low-severity threat to persistence, and a final ranking of “potential risk” to become extirpated (Table 26). More recent analysis by High et al. (2008) determined that a significantly positive rate of population change occurred pre- 1994, and post-1994 was stable overall, indicated by the near zero rate of change (19 years of record at 26 sites).

Lower and Middle Fork Clearwater River Core Area Adult and subadult bull trout probably use the lower (mainstem) Clearwater River, Middle Fork Clearwater River, and their tributaries primarily as foraging, migratory, subadult rearing, and overwintering habitat, although the extent of use is unclear. Bull trout abundance is at very low

Page 90

levels within this core area. No tributary streams have current documentation of bull trout spawning; however, Lolo Creek has documented occurrence of juvenile bull trout. Lolo Creek is considered a local population because some small juveniles have been found above a small falls that would preclude fish of their size from migrating upstream to this location. Clear Creek is the only potential local population. In Clear Creek, 2 to 4 bull trout are collected annually at a salmon trap during spring and released above the trap. Length of captured bull trout has been 254 to 356 mm.

The bull trout 5-year status review conducted in 2006 (USFWS 2008) determined the Lower and Middle Fork Clearwater River Core Area had an unknown adult abundance level, occupation of stream miles in the 125-650-mile range, an unknown short-term trend, substantial/imminent threat to persistence, and a final ranking of “at risk” to become extirpated (Table 26). This core area was not evaluated by High et al. (2008).

15.3 ANALYSIS OF EFFECTS

Direct Effects

Direct effects primarily arise through collection of spring Chinook broodstock. Migratory bull trout are captured in the Crooked River trap, Walton Creek trap, and Clear Creek trap targeting spring Chinook salmon. A variable number of upstream migrant bull trout are captured, bio- sampled, and passed upstream of these traps each year. Traps may also have a short-term effect through potential alternation of migration routes or delay in movement.

A small percentage of bull trout sampled in a fish trap may be injured or killed (generally less than 1%) as evidenced by the very small level of mortality reported by IDFG (IDFG 2006, 2007, 2008, 2009). Adult trapping activities have occurred for many years in the Clearwater River subbasin and have not apparently hindered positive population growth rates of bull trout since 1994, as evidenced by results of High et al. (2008), and are not expected to limit bull trout population growth rates into the future.

Competition is possible between subadult bull trout and hatchery spring Chinook juveniles if some residualize. Because these species evolved sympatrically in the Clearwater River subbasin, some form of resource partitioning would be expected. In addition, Chinook salmon residualism is suspected to be an uncommon life history strategy. Therefore, potential competition is not expected to be a primary limiting factor for bull trout. On the contrary, release of juvenile hatchery Chinook likely provides increased forage (beneficial effect) for migratory adult and subadult bull trout, which are highly piscivorous.

Indirect Effects

Indirect effects may arise through hatchery operations such as water withdrawals, effluent discharge, routine operations and maintenance activities, non-routine operations and maintenance activities (e.g., intake excavation, construction, emergency operations, etc.). Hatchery operations are not expected to affect bull trout population productivity. These activities have occurred for many years in the Clearwater River subbasin and apparently haven’t hindered positive population growth rates of bull trout since 1994, as evidenced by results of High et al. (2008), and are not expected to limit bull trout population growth rates into the future.

Page 91

Cumulative Effects

Cumulatively, the effects of the Clearwater spring Chinook hatchery program and associated monitoring and evaluation results in increased forage for migratory adult and subadult bull trout and contributes knowledge on bull trout population distribution and abundance through incidental captures in broodstock collection traps. Such knowledge can be used to evaluate bull trout population trends over time, such as the analysis conducted by High et al. 2008.

Take

Annual bull trout take in the form of observation, capture, handling, and bio-sampling occurs each year at various broodstock collection traps and through associated monitoring and evaluation studies. At the end of each year bull trout take is quantified and projected for the upcoming year’s operations and monitoring in a report prepared by IDFG (the Idaho Bull Trout Conservation Plan and Take Report). Take is derived from observing or capture and handling of bull trout through a variety of survey methods, including snorkeling, redd surveys, electrofishing, hook-and-line, weir trapping, screw trapping, and seining. Between 2005 and 2009 inclusive, a total of 134, 68, and 3 bull trout were captured at Crooked River, Powell, and Red River adult trap respectively. During the same time period, no incidental mortality of bull trout associated with trapping operations occurred.

15.4 ACTIONS TAKEN TO MITIGATE FOR POTENTIAL EFFECTS

Actions taken by IDFG to minimize adverse effects on bull trout include:

1. Continue fish health practices to minimize the incidence of infectious disease agents. Follow IHOT, AFS, and PNFHPC guidelines.

2. Monitor hatchery effluent to ensure compliance with National Pollutant Discharge Elimination System permit.

3. Continue Hatchery Evaluation Studies (HES) to provide comprehensive monitoring and evaluation for LSRCP Chinook, which provide valuable incidental bull trout data.

4. Conduct adult trapping activities to minimize impacts to bull trout and other non-target species. Trapping provides valuable incidental bull trout data.

5. Prepare annual bull trout conservation program plan and take report, submitted to USFWS, to ensure compliance with the ESA.
